Two weeks ago, New Zealand’s Deputy Prime Minister, Carmel Sepuloni, confirmed that the age of entitlement for NZ Super would remain at 65 under a Labour government. This contrasts with the National Party’s commitment to raise the age to 67 if it wins in October.
Narrow self-interest being a major driver of voting behaviour, this could well be a significant issue in the coming election.
It’s interesting to consider this issue in the context of what happens in Australia.
Fourteen years ago, the age of eligibility for the Australian state pension was 65. However, in 2009 a Labor government introduced a transitional process to gradually raise the age over the period from 2017 to 2023. That process will be complete at the end of this month, and from 1 July the age of eligibility will be 67.
The rationale for the increase was fiscal responsibility. The demographics were compelling and rendered a pension age of 65 financially unsustainable.
The threshold of 65 was set way back in 1908 when most people weren’t expected to live that long. Today it’s a completely different story. Life expectancy has increased dramatically in Australia and is now closing in on the mid-80s. Someone who reaches 67 today is likely to live for another two decades.
No wonder they say 60 is the new 40. And on that basis, 65 is probably too young for a state pension.

Climbing life expectancy in Australia, combined with various factors such as women having fewer children, has had, and continues to have, another important consequence – a dramatic rise in the percentage of the population aged 65 and above.

Such a rapid increase in the proportion of the population who meet the qualifying age for the pension can have a major impact on the fiscal sustainability of any taxpayer-funded pension scheme – fewer taxpayers for every pensioner.
In its 2014 budget, the Coalition government proposed increasing the qualifying age for the pension even further than the previous Labor government had done – from 67 to 70 by 2035. According to the Treasurer at the time, demographics and economics meant there was no alternative.
However, as is often the case, political necessity trumped fiscal responsibility. The Australian Senate would not agree to the proposed second pension age increase. In 2018, the Coalition government abandoned the policy altogether.
Therefore, the qualifying age will be 67 from 1 July with no further increase currently advocated by either side of politics.
Nevertheless, the pension funding issue is not going away. Just last month, the Macquarie Business School (MBS) published a statistical analysis of the issue and recommended that the age of pension eligibility be raised to 68 by 2030, 69 by 2036, and 70 by 2050. According to the MBS analysis, these increases are required if the pension system is to remain sustainable without increasing the burden on taxpayers.
However, the issue of fiscal sustainability was analysed by Treasury as part of its Retirement Income Review (RIR), a comprehensive review of the Australian retirement system in 2020/2021. The final report of the RIR concluded that ‘government expenditure on the age pension as a proportion of GDP is projected to fall slightly over the next 40 years to around 2.3 per cent’. That figure assumed no further lift in the pension eligibility age.
How is that possible given the ageing population? The answer lies in the second major difference between the Australian and NZ pension systems. In Australia, the pension is means tested.
Entitlement to the pension phases out at different asset and income levels. Broadly speaking, a single person is not entitled to any age pension if their income exceeds A$60,000. The threshold for the assets tests depends on whether a person owns their own home. If they do, a single person is not entitled to any age pension if their assets (excluding their home) exceed A$634,000. If a person isn’t a homeowner, the threshold is A$859,000.
These means tests disqualify many Australians from receiving the age pension. According to Treasury, in 2019 only 71% of Australians over the pension eligibility age received the age pension or other pension payments. Significantly, that proportion is forecast to fall to just 62% by 2060.
And how is that possible? As the means test thresholds are appropriately indexed, it’s not a result of inflation. Instead, it primarily reflects increasing numbers of Australians failing the assets test because of the value of their superannuation investments.
This is the third key difference between Australia and NZ. Australia has a compulsory superannuation system that has been in place since 1992. Broadly speaking, an employer must pay 10.5% (rising to 11% next month) of an employee’s ordinary earnings into a superannuation fund. Voluntary contributions can also be made.
A crucial aspect of the system is that it is very difficult for a person to access their super until they are in their 60s. The system is intended to force people to save money for their retirement.
The result is that in 2023 Australians collectively hold over A$3.5 trillion in their super accounts. That constitutes the fifth largest pension market in the world. That has many advantages including the provision of vast amounts of capital available to fund infrastructure assets onshore and an exposure to international assets as large Australian super funds inevitably go offshore to find suitable investments.
Importantly, it also reduces the cost of the pension system to the taxpayer as more and more Australians fail the assets means test due to their superannuation savings. As Treasury concluded in the RIR, ‘this is expected to reduce the cost of the Age Pension borne by the next generation’.
There’s only one problem. The superannuation system includes numerous tax concessions both to compensate Australians for the compulsory nature of the system and to incentivise them to make additional contributions. The rising cost of those concessions to the budget undermines much of the fiscal benefit of reducing reliance on the age pension.
In the last budget, the Labor government wound back some of those super-based tax concessions. More work is required. Unfortunately for the government, it’s politically unpopular and therefore electorally dangerous. A bit like increasing the pension eligibility age.
