A $5000 KiwiSaver nest egg at birth. Is this the radical retirement rethink we need?
Saturday, 28 February 2026
Most of us don’t realise that our KiwiSaver is handcuffed to superannuation.
If the eligibility age for NZ Super rises to 67 or 70, your KiwiSaver access moves with it.
Current legislation couples the two arms of our retirement system. They exist and move in tandem.
This is just one of the many observations former Mercury Energy chief executive Fraser Whineray has made as he’s dug into the details of KiwiSaver.
“KiwiSaver access needs to have its own date,” says Whineray.
“It could come earlier, but it can’t come later.”
Whineray has long been a supporter of KiwiSaver, but says good policies should evolve over time in line with a clear strategy.
Politicians in government tend to tinker with its settings every few years, which, according to Whineray, has the effect of diluting its effectiveness.
We’ve seen incentives for contributions reduced, we’ve seen the introduction of total remuneration clauses, and we’ve seen minimum contribution rates reduced and then increased. Each of these changes has been driven by the Government of the day, and ultimately affects how KiwiSaver works for you. This all matters because KiwiSaver will only become more important over time as a means for New Zealanders to secure their long-term wealth.
What Whineray wants is for the system to be strategically improved so that Kiwis are in a far better position in the coming decades.
The tale of two Maias
Whineray’s thought experiment pits 'Current Maia' against 'Future Maia.'
Under the current settings, Maia could start contributing from the age of 16 to qualify for the government subsidy of $260. By the time this child has reached adulthood, what little they’ve been able to put in would not have been given any time to compound.
Whineray doesn’t think it needs to stay this way.
His solution? A $5,000 birthright investment for every newborn.
By age 18, compound growth would have turned that $5,000 into $20,000, providing a first-hand lesson in the power of time in the market.
But how do we pay for this?
Whineray suggests a simple swap to fund this: scrap the $260 annual government contribution for adults and redirect it to newborns.
Since its inception, the government contribution has dwindled from $1,042 to $260. It currently costs $500 million a year, and time is ticking on how much longer this incentive will even exist.
Whineray argues that rather than letting this money vanish into the Crown’s accounts, we should pivot. His plan costs roughly $300 million for newborns, with the remainder covering parental leave gaps ($35-60 million) and a $100 annual match for children ($120 million).
Whineray says transferring these funds is cost-neutral and will deliver far better returns for New Zealand in the long term.
It’s about being smarter in the way we use taxpayer money.
Rebalancing the burden
As New Zealand’s population ages, so too does the burden of paying superannuation. NZ Super currently costs approximately 5% of GDP, a figure projected by Treasury to rise to 8% by 2060.
To pay for this, the money will have to come from somewhere – be it health, education, public works or access to life-saving drugs. The alternative is raising this Super age, but this is only one part of the equation.
The only way to lessen that dependency on Super is by shifting the balance in our retirement system, so that Kiwis have more wealth accumulated by the time they retire.
While any rebalancing must be done carefully to ensure the rug isn’t pulled from under retirees who haven’t had the time to save sufficiently, Whineray wants to see deliberate action right now.
“We need to get to 12% faster,” says Whineray, explaining the need for New Zealand to move to a position where we have mandatory employer contributions at 12% – as seen in Australia.
Steadily increasing contribution rates in Australia has led to Australians saving up far more for retirement. By the age of 65, an Australian today will have between A$400,000 ($475,000) and A$450,000 ($534,000). Our comparably low contribution rates combined with the shorter lifespan of KiwiSaver means the average Kiwi has only about $69,000. We have a lot of catching up to do, and we don’t have the luxury of a long run way to get there.
“We need to get there in about 20 years… Lifting KiwiSaver contribution rates has to be done very gently, because otherwise it could have some problematic economic outcomes. It took Australia 30 years to get to 12%. They only got there last year, so predictability, I think, is key.'
The National Government has proposed increasing the employer contribution to 6% by 2032, but Whineray doesn’t want it to stop there.
The steady incremental increase needs to continue so that we have actual parity with Australia (bearing in mind that Australia may push its contribution rate up a little further).
Closing the self-employed gap
Infometrics data shows around 423,000 New Zealanders are self-employed.
These individuals often fly under the radar in the KiwiSaver debate, but Whineray thinks it's important to ensure they aren’t left behind.
Whineray would like to see mandatory contributions also applied to the “worked income” self-employed workers disclose to the Inland Revenue Department (IRD).
A set percentage of that worked income should go to KiwiSaver to ensure that everyone is saving incrementally over time.
He would also like to see self-employed workers qualify for government-funded parental leave contributions under his reworked KiwiSaver.
Self-employed workers may be concerned about the impact this could have on their cashflow and earnings over the course of a year – and that’s fair enough, but this could apply equally to anyone contributing a percentage of their salary to KiwiSaver every month.
Australia has responded to these concerns by keeping contributions voluntary but giving these workers strong tax incentives to contribute.
Whineray admits requiring self-employed workers to contribute may lead to inflation in the price of the services they offer, but the priority should be on ensuring that all New Zealanders save incrementally as they age.
Will my retirement rules change every election?
No matter who you speak to about our retirement system, they generally agree that Kiwis need the system to be predictable so they can plan accordingly.
So much of this depends on political alignment between political parties. We’ve seen how governments with different views are capable of diluting KiwiSaver over time to appease their constituents.
Whineray wants to see even more than simply bipartisanship, which often relies on a fragile compromise between both sides.
For the policies to work, he says, they need to be “politically ambidextrous” so that politicians from either side of the aisle can champion them.
“The same dish should be served to constituents in different ways,” says Whineray, explaining that this is key for a policy to endure beyond a single party’s run in power.
“If you look at the laws that have lasted a long time, they have been designed for constituents beyond those who supported the government of the day.”
