Use of four major tobacco control interventions in
New Zealand: a review
Nick Wilson, George Thomson, Richard Edwards
The international literature reports high quality scientific
evidence for a number of the population-level tobacco control interventions used
in New Zealand.1 In many cases, there is
supportive New Zealand-specific evidence for such interventions being
effective.1 Aspects of New Zealand’s
overall tobacco control programme have been reviewed
previously,2-5 but not since 2000.
New Zealand ranks ninth lowest among the 30 OECD countries
for adult smoking prevalence,6 but prevalence
is considerably higher than in the leading countries, with for example an
absolute gap of over 6% compared to countries such as Australia (at around
17%)6 or Sweden (around
16%).7 Also, the overall adult smoking
prevalence for New Zealand masks large disparities between population groups,
with for example, very high adult Māori smoking rates (46% in 2006) which
have changed little over the last 20 years or
more.8 Some other OECD countries have also had
much steeper declines in smoking prevalence rates compared to New Zealand (e.g.
Canada and Sweden—see Figure 1).
The persistently high and slowly declining smoking
prevalence in New Zealand and increasing disparities in smoking prevalence by
ethnicity and socioeconomic position highlights the need to critically examine
New Zealand’s tobacco control efforts. This review aimed to compare the
extent to which four best practice population-level tobacco control
interventions are being used in New Zealand, and in comparison with other OECD
countries.

data9 and two New Zealand data
sources8 10 (with both countries reporting data
for 2006 and prevalence for both daily smokers and non-daily smokers combined).
A different survey methodology was used for the 2006
data8 in New Zealand. The results for Sweden
are for daily smokers and are for
2004–2005.7
MethodsSelection of major
interventions—For this article we selected the four
population-based interventions that were best supported by evidence for
effectiveness from either a Cochrane systematic review or a systematic review
undertaken by a United States Task Force (as reviewed
elsewhere1). These were:
As the focus
for this review was on population-level interventions, we did not consider
programmes for individual-level provision of smoking cessation advice and
support (e.g. Quitlines, although Quitline advertising is covered within mass
media campaigns, since such campaigns may stimulate quitting that is independent
of cessation service usage).
We recognise that there are many other tobacco control
interventions where there may be benefits for tobacco control, but where the
evidence-base is not as well established (e.g. school-based health education,
age limits on purchasing/use of tobacco, smokefree sponsorship, and increasing
unpaid media coverage of tobacco-related matters).
There are also interventions that can address upstream
societal determinants of smoking such as poverty, inequality, poor education,
unemployment, and discrimination. However, these were out of the scope of this
review. More radical tobacco control strategies such as reforming the structure
of the tobacco industry or market are also not included in this review, as they
are without an established evidence-base. However, such new
strategies11–14 need serious
consideration in designing future tobacco control policy, either beside or
overarching “traditional” and evidence-based tobacco control
interventions that are the focus of this review.
We also recognise a particular need to review tobacco
control policies for Māori, given the very high smoking prevalence rates of
Māori. Such a review is being currently undertaken by our Māori health
research colleagues.
Literature searches—To identify
relevant New Zealand data, we undertook Medline searches for articles relating
to tobacco control interventions, using the search terms “Zealand”
and “smoking or tobacco” for the period January 2000 to 30 June
2007.
To identify New Zealand literature that was not
Medline-indexed, the following websites were examined for reports and studies:
the Ministry of Health, the Quit Group, the Health Sponsorship Council, the
Cancer Society, the Heart Foundation and ASH (New Zealand). Non-Medline indexed
literature was identified with the search engine Google Scholar.
Analysis of each major
intervention—For each of the major interventions, we aimed to
determine the extent to which the intervention was being applied relative to
best practice within other OECD countries. Comparisons for the other 29
countries who were OECD members in 2006 were generally based on The
Tobacco Atlas6 (but with other sources
cited where appropriate).
ResultsThe evidence-base on tobacco taxation in this country has
been reviewed previously.15,16 We reviewed the
implementation of tobacco taxes in New Zealand during the study period.
New Zealand’s tobacco tax level as a proportion of the
pack price was only 19th out of 25 OECD
countries for which data were published in
2006.6 A more relevant comparison considers
relative purchasing power to indicate affordability of tobacco products. A year
2000 comparison ranked 22 OECD countries using the “Big Mac index of
cigarette affordability”, and ranked New Zealand as having the third most
expensive cigarettes.17
A similar analysis published in 2002 found that New Zealand
cigarettes were the most expensive of all OECD
countries,18 and that Marlboro and “local
brand” cigarettes in New Zealand were both the fifth most expensive among
all OECD countries when ranked by minutes of labour required to buy a packet. In
2004, an analysis that included 28 OECD countries ranked affordability using
pack price in relation to GDP per capita. It found New Zealand cigarettes were
the second most expensive after Turkey, one of the poorest OECD
members.19
More recent published analyses were not available, so we
obtained 2005 price data for a pack of Marlboro cigarettes in New Zealand and
for EU countries in the OECD (using supplementary online data from a published
article20 and using GDP data per capita for
2005 from the IMF to allow for purchasing power
parity-adjustments21). The adjusted New Zealand
price was more expensive than all the 22 other European OECD countries except
for the UK which was only slightly higher.
Despite these high tobacco prices in New Zealand, various
other aspects of the price/tax intervention are underused, compared to other
jurisdictions. Firstly, there are very infrequent increases in tobacco tax above
the annual inflation-adjustment [none for over 7 years (i.e. since May 2000) and
only two above-inflation rises in the tax on manufactured cigarettes since
1991].
Secondly the tax is not tied to funding for tobacco control
or health-related activities. This is despite examples of the successful use of
dedicated taxes within OECD jurisdictions, and the evidence that voters are more
likely to support such taxes.15,22 Thirdly,
there is no evidence of other measures to maximise the effect of taxation
increases as a public health intervention (e.g. concurrent media campaigns on
smoking cessation when tax increases occur).
Finally, the impact of price appears to be being undercut by
the very high proportion of smokers who now smoke roll-your-own cigarettes in
New Zealand (60% of Māori smokers and 49% of European/Other ethnicity
smokers,8 which are very high levels compared
to other OECD countries23). This means that
without any additional tax on loose tobacco, smokers can keep smoking (for the
same expenditure after a price increase) by rolling thinner cigarettes with
around half the amount of tobacco of factory-made
cigarettes.24
Existing controls on tobacco marketing were slightly changed
in 2003 with the Smoke-free Environments Amendment Act (SEAA), which introduced
further restrictions on tobacco displays at the point-of-sale. These included
restrictions on the number and type of tobacco packets and cartons which can be
displayed, and requirements that tobacco displays should not be visible from
outside the shop, and should not be within a metre of sweets and other
children’s products. The Framework Convention for Tobacco Control, which
New Zealand ratified in 2004,25 requires
comprehensive bans on tobacco advertising and
promotion.26
New Zealand’s controls on tobacco marketing compare
favourably with most other OECD countries. A comparison using 2005 data
suggested that New Zealand was one of 17 OECD countries (out of 30) to have
advertising restrictions on television, radio, and in domestic print
media.6 Also in 2005, New Zealand was one of
only four OECD countries to be classified in The Tobacco Atlas as
having a “comprehensive advertising ban”—including billboards,
point-of-sale advertising, and event
sponsorship.6
Nevertheless, tobacco marketing has not been completely
eliminated. Block displays of up to 100 packs of cigarettes per point-of-sale
are still permitted, and tobacco products are prominently displayed in almost
all of the most commonly used retail environments—dairies, convenience
stores, supermarkets, and petrol stations. More rigorous interventions used in
some OECD countries are not used in New Zealand. For example,
Iceland,27 and five Canadian
provinces,28,29 have point-of-sale product
display bans.
By requiring large warning labels, other countries also
displace more marketing images from the front and backs of tobacco packs than
does New Zealand. In 2005, New Zealand lagged behind 15 OECD countries which had
health warnings that were required to cover 30% or more of the
pack.6 New Zealand is adopting graphic warnings
during 2008, but these still only cover 30% of the front of the pack (the most
significant surface for smokers), compared with 50% in Canada. This is despite
the evidence-base for the impact of large size Canadian graphic warnings on
smokers.30,31
Descriptors such as “light” and
“mild” are marketing devices to reassure smokers and suggest that
such cigarettes have less adverse health
effects.32 These descriptors are banned in at
least 23 OECD countries33 and will shortly be
in Canada also.34 “Light and mild”
descriptors are not banned in New Zealand, although this issue is subject to a
current (2008) Commerce Commission Enquiry. The Commission has however, chosen
to ignore the issue of “brand
names”,35 despite these also being
potentially misleading—e.g. the “Freedom”
brand.36
Colour coding also appears to be being used by tobacco
companies in New Zealand to signal “light and mild”
cigarettes37 (possibly in anticipation of a ban
on the descriptors), and this issue may also be outside the Commerce
Commission’s considerations.
Mass media campaigns have been extensively used
internationally and in New Zealand for tobacco control. We reviewed the use of
tobacco control mass media campaigns at a national level in New Zealand since
January 2000. Not included are more local community level mass media campaigns,
or where media are used to promote regional quit and win contests.
Recent mass media campaigns have focused on promoting
smokefree workplaces, homes and cars; promoting quitting (including calling the
national Quitline); explaining the new smokefree law (the SEAA 2003); and
promoting smokefree messages to Māori and Pacific peoples (for details see
the Quit Group and Health Sponsorship Council websites and the website: www.secondhandsmoke.org.nz).
One analysis detailed national-level monthly mass media
campaign expenditure for three 12-month periods (late 2002 to late
2005).38 From this source, the average annual
expenditure can be calculated to be $2.3 million by the Quitline and $2.8
million for other agencies (e.g. the Health Sponsorship Council), and represents
around $NZ 1.20 per capita per year. When this amount is adjusted by relative
purchasing power (using GDP per capita values for New Zealand and the United
States) it equates to only $US 0.57 per capita. This can then be compared with
data from particular US states, which have reported two to four times higher per
capita advertising expenditures for youth campaigns alone (i.e. $US 2.35 per
capita for Arizona, $US 2.16 for Massachusetts, and $US 1.29 for
Florida39) or for all campaigns combined (e.g.
$US 1.32 per capita for 2000/01 in
California).40
Nevertheless, the available literature on the New Zealand
campaigns41-44 suggests that some campaigns are
well targeted for priority audiences and are well designed. For example:
When compared to other OECD countries
however, it is possible to identify potential for improvements in the New
Zealand mass media campaigns. These include the following:
Furthermore,
there is some evidence for the deliberate constraint of resources allocated to
mass media campaigns to prevent excessive demand on the Quitline Service, such
as following the implementation of the smokefree workplaces and public places in
December 2004.53 Instead, there should be an
increase in funding of mass media campaigns at such times to exploit the
synergies of co-interventions coupled with an increase in resources for
cessation support to address the increased demand.
From an international perspective, New Zealand’s
smokefree law of 1990 was an advanced piece of tobacco control legislation. The
updated 2003 legislation (implemented during 2004) extended smokefree areas to
all restaurants, bars, and other indoor workplaces (except for prisons cells,
and designated smoking rooms in health care institutions, residential disability
care institutions, or rest homes). It also prohibited smoking in schools and
early childhood centres, in taxis and other public transport, casinos, and in
gaming machine venues. Smoking in outdoor settings is prohibited in the grounds
of all schools by this legislation.
Local regulations or policies initiated by some local
governments (Territorial Local Authorities) cover some council-owned parks (e.g.
in South Taranaki and Upper Hutt), the grounds of some hospitals, some stadiums,
and the campuses of a university (Massey).
In 2005, New Zealand was one of only seven OECD countries to
have a full ban on smoking in government
buildings.6 In 2004 it became the third country
in the world to ban smoking indoors in bars and restaurants (after Ireland and
Norway), though this legislation was a decade behind that for
California.54
In 2007, New Zealand was still one of only 10 OECD countries
with comprehensive indoor workplace smoking bans that included bars and
restaurants (though some other OECD countries such as Australia and the US have
state-wide bans).54
Table 1 details the range of environments covered by
smokefree regulations. These are relatively broad compared to most other OECD
countries. Nevertheless, in certain ways the New Zealand coverage of smokefree
environments lags behind. For example, there are a number of jurisdictions where
smoking is banned outside on beaches, in parks, playgrounds, stadiums, bus
shelters, the outdoor sections of hospitality venues, common areas of housing
estates, and in the outdoor areas of a whole town in
California.55–58
More specifically, these restrictions include all
Californian public playgrounds;59 public
playgrounds in over 20 New South Wales local
authorities;60 and all park, sports fields,
playgrounds, beaches, and bus shelters in parts of
Sydney.61,62 A number of jurisdictions also ban
smoking near building entrances—e.g. Washington State in the United
States.63 Some of these approaches will
probably reduce secondhand smoke exposure in crowded settings, but more
importantly, they may reduce the visibility of smoking to children and hence
contribute to preventing role modelling of smoking to children and the
denormalisation of smoking within society.
There has also been no proposal by the New Zealand
Government for a law for smokefree private cars, and yet a number of
jurisdictions have introduced such restrictions—where children are in the
vehicle. These include South Australia, Arkansas, Louisiana, Puerto
Rico,64 and the city of Bangor (Maine,
USA).65

DiscussionMain findings and interpretation—The
major finding of this review is that there is still scope for further progress
in all these four key tobacco control areas in New Zealand. There is a strong
public health argument for increased investment to achieve such progress, given
the major impact of tobacco use on premature mortality in this
country,71 its adverse impact on Māori
health, and its contribution to health
inequalities.72 The argument is supported by
the relatively poor results of government efforts to reduce the smoking
prevalence, compared to countries such as Australia, Canada, and Sweden.
Although New Zealand has relatively high tobacco prices, it
is a concern that New Zealand is not using tax policy to prevent smokers from
shifting to thinner roll-your-own cigarettes,24
rather than quitting. This problem could be partly addressed by adding a
differentially higher tax for loose tobacco (so that it leads to a similar price
for thin roll-your-own cigarettes and standard factory-made cigarettes).
Furthermore, there has been no real increase in levels of
taxation for over 7 years. Given the proven effectiveness of tobacco
tax73 and its ethical
justification,74,75 this situation should be a
priority one for health agencies and advocates to address. Indeed, the Ministry
of Health’s 5-year plan for tobacco control specifically identifies
tobacco taxes as “the most important single intervention to reduce smoking
initiation”.76
However, there are some gaps in the information required to
inform best practice in the use of tobacco taxation policy for prevention of
smoking among youth and reducing smoking in high prevalence communities such as
Māori. For example, there is very little information on how tobacco price
impacts on Māori smokers, and on low socioeconomic position smokers in New
Zealand. There are few New Zealand studies that consider the impact of youth
income and tobacco prices on youth
smoking.77–80
Other important areas for New Zealand to catch-up with OECD
leaders include eliminating point-of-sale product displays, removing misleading
descriptors, and using larger areas of packs for warning labels. In the mass
media campaign area, there is scope for learning from countries that have used
tobacco industry focused campaigns, and for a large increase in the resources
allocated to sustained and targeted mass media campaigns using best practice
methods. In particular, there is a need for a greater focus on campaigns that
reach Māori and Pacific audiences (though this is to be the subject of a
separate review).
By being the third country in the world to implement
extensive smokefree workplaces (including restaurants and bars) there may be a
sense among New Zealand policymakers that the smokefree environments issue is
“solved”. However, the normality for a significant proportion of
adults and children of being exposed to tobacco
smoke,8,81 particularly in homes, means that
measures are urgently needed to reduce children’s exposure to SHS and the
role-modelling to children of smoking as an adult behaviour. This is crucial,
given the evidence of the influence of smoking around children on smoking
initiation,78,82–87 and the policy
emphasis within the Government’s Framework for Reducing Smoking
Initiation in Aotearoa-New Zealand.88
Measures could include:
The context behind the policy
shortfalls—It is possible that New Zealand policymaker focus on
introducing and operationalising the smokefree environments law (SEAA 2003) has
diverted attention away from the need to have an effective overall strategy.
Public health worker and policymaker attention has also been diverted to such
key public health issues as the obesity epidemic and climate change. Another
contributing factor to the slow progress in some areas may be the political
situation, in that the dominant political party (Labour) in recent years has had
to fight hard in Parliament for tobacco control advances (i.e. the SEAA 2003).
In particular, the minor parties in the government coalition
since 2002 (United Future), and since 2005 (United Future, New Zealand First),
do not appear to be natural allies in tobacco control progress. That is, 19 out
of 21 MPs in these parties voted against the SEAA and one leader has a long
history of opposition to tobacco control.89
The Labour-led Government may not have felt it had
sufficient political support from other parties in the MMP government, and
sufficient public support to make additional bold moves on such issues as
tobacco tax reform. But from a public health perspective, a government that
better informed the public of the issues would probably be able to
better engender increased public support for more rapid progress on tobacco
control.
Limitations of this review—This
review may not have identified some of the grey literature relating to the
utilisation of these interventions in New Zealand (e.g. internal documents that
organisations had not published on their websites). The comparisons with other
OECD countries were also incomplete, as it is often years before the details of
particular policy interventions are detailed in the Medline-indexed literature.
Others have also taken a slightly different approach to
inter-country comparisons for tobacco control, using a scale with six
interventions, adding to the ones we have used the use of large warning labels
on packs and smoking cessation treatment (but with these two extra categories
having a lower weighting).20
We are also aware that this review has not fully considered
issues around synergies between different interventions. Nevertheless, in the
areas where such synergies could clearly have been exploited, these appeared to
be poorly developed in New Zealand. For example, when the new smokefree law was
introduced in 2004, Quitline mass media expenditure actually
decreased!38 Furthermore, there was no special
mass media campaign for quitting at the time of the last substantive tobacco tax
increase in 2000. Mass media campaigns for smokefree cars have also not been
accompanied with legal requirements for such cars to be smokefree when children
are present.
The issue of synergies, and the limitation of excluding
other interventions where the evidence-base is not as well established, become
particularly important when the question is posed of the causes of New Zealand
poor performance in reducing smoking prevalence, when compared with similar
jurisdictions in the last 15 years.
In addition to Canada and Sweden (see Figure 1), there has
been particular progress in lowering prevalence rates in particular states and
provinces within OECD countries. That is California, British Columbia, and New
South Wales have reached daily smoking prevalence rates below 10%, 12%, and 14%
respectively (albeit with minor variation in definitions of
“adult”).90 Thus California, with
less use of marketing controls, an earlier use of smokefree laws, and
more use of mass media, has a daily rate of less than half that of New
Zealand. Thus the particular mix of interventions may be a major factor
in tobacco control effectiveness (along with differing social and economic
contexts).
Furthermore, one of the significant differences between
Canada, USA, Australia, and New Zealand, is the much greater degree of
litigation against tobacco companies and around smoking harm in the former
group.48 It is possible that such factors such
as litigation,91 and the type and extent of
coverage of tobacco issues in the
media,92–94 are as significant as any of
the four major interventions that we have focused on.
Implications for policy and
research—The clear implication from this review is that much more
progress in all the four intervention areas that we focus on is necessary, and
that synergies between them should be maximised. One counter argument however,
is that attention to these established areas distracts from achieving the key
structural changes that may deliver more rapid progress (as mentioned in the
Methods).
Such structural approaches are possibly more rational than
incremental change in specific intervention areas—but they may also be
much harder to achieve politically. Therefore health advocates may wish to run a
mixed strategy of getting high level structural change onto political agendas,
and pushing for them when the political situation is favourable, but focusing on
specific priority interventions at times when political will is weak and
fragmented.
ConclusionsThe major finding of this review is that there is still
substantial scope in each of these four key tobacco control areas, for New
Zealand to make progress to the level of OECD leaders. In particular, New
Zealand needs to increase tobacco tax levels for loose tobacco (to equate to
that on factory-made cigarettes at the per cigarette level). Further elimination
of residual marketing (e.g. at point-of-sale displays) and the removal of
misleading descriptors on tobacco packaging, are also needed. There is also
potential for achieving greater synergies between the major interventions.
