Generational fault lines deepen over New Zealand Superannuation as costs climb

HouGarden New Zealand, 14 October — New Zealand Superannuation, known as NZ Super, is a government pension paid at a fixed weekly rate to all eligible New Zealand residents aged 65 and over. Unlike many comparable schemes around the world, it carries no means test and no asset or income threshold: every qualifying resident receives the same amount regardless of wealth or employment history. That universal design is now at the centre of an intensifying debate about long-term affordability.

NZ Super currently costs the government approximately NZ$26 billion a year. That figure represents roughly one-fifth of New Zealand's total annual tax revenue of around NZ$130 billion, according to figures cited by Cameron Bagrie, founder of independent economic consultancy Bagrie Economics.

Alec Waugh, speaking on behalf of the KiwiSaver Annuities New Zealand Superannuation Protection Society — a lobby group that advocates for preserving the existing pension system and is not a government body — argues that calls for reform may be underestimating the knock-on costs of change. 'At 4.4 percent of GDP net super, New Zealand's scheme is one of the cheapest, efficient and effective schemes, near half the costs of other countries schemes,' Waugh said. He pointed to Australia's means-tested system as comparatively complex and noted that government tax credits for investors in that model come at significant fiscal cost.

Bagrie does not dispute that 4.4 percent of GDP is a relatively low figure by international standards. His concern is the direction of travel. 'Whether it's 2 percent, 4 percent, 6 percent or 8 percent of GDP is somewhat irrelevant because what you're looking at, if it takes up more share of GDP, we face choices because in order to fund that you're either going to have to crunch another part of government expenditure or you've got to lift taxes,' he said.

Bagrie acknowledged that the increase in NZ Super as a share of GDP has so far been less dramatic than some earlier projections suggested, partly because strong immigration-driven economic growth has bolstered the overall GDP base. But he said the underlying demographic shift cannot be papered over indefinitely.

The key metric Bagrie points to is the dependency ratio — the number of working-age New Zealanders for every person receiving NZ Super. Thirty years ago that ratio stood at seven to one. It has since fallen to four to one and is projected to decline further to two to one. In practical terms, that means each worker will eventually be supporting a far greater share of pension costs than their parents or grandparents did.

'One of the ways we've protected it is that we've just got a lot more GDP growth from immigration,' Bagrie said. 'What's called the dependency ratio has come on a little bit better than expected. But 30 years ago the dependency ratio was seven to one. Now it's four to one and it's projected to decline to two to one.'

Bagrie frames the debate in explicitly generational terms. Baby boomers who accumulated wealth through rising property values face younger New Zealanders who cannot afford to buy a home at today's prices. That divide, he argues, explains the differing attitudes toward a capital gains tax or a wealth tax. 'The younger generation like the idea of a wealth tax or a capital gains tax whereas it scares the bejesus out of the boomers,' he said. 'How do you explain to that generation that can't afford to jump on the property ladder that you're going to be funding the boomers' retirement?'

He said younger voters' sense that the system was not working for them was likely driving interest in minor political parties. The contrast he draws is blunt: the generation now retiring benefited from free tertiary education, while today's workers took on student debt and are now expected to fund their predecessors' retirement. 'Did you get a free education? This generation don't get a free education and now they're expected to get out in the workforce to fund the boomers? Back the truck up here,' Bagrie said.

Shamubeel Eaqub, chief economist at low-fee KiwiSaver provider Simplicity, agrees that the GDP comparison can obscure the real pressure. He argues the more meaningful measure is how NZ Super's cost compares to the tax base, not to the overall size of the economy. 'With ageing, the tax base gets smaller and the super cost gets bigger, as well as health and many other promises,' Eaqub said. 'You can't say that super must be kept as is and tax just increased to 50 percent on workers of tomorrow. Why should they?'

Eaqub added that if changes are made, they would almost certainly need to apply to future generations rather than to people already in or close to retirement, because people need adequate time to plan and adjust.

Matt Roskruge, an economist at Massey University, offered a different angle on the scheme's design. Even though NZ Super places relatively few restrictions on who qualifies, he noted it is not a particularly generous payment in absolute terms. That means it leaves retirees without savings or other assets in a financially vulnerable position — while simultaneously continuing to support retirees who hold significant wealth and investment income.

Politicians are currently debating a range of possible reforms, including raising the eligibility age and making KiwiSaver contributions compulsory. Discussions around a capital gains tax and a wealth tax also remain active. No policy changes in any of these areas have been legislated or confirmed, and all proposals remain at the stage of public and parliamentary debate.
