COMPULSORY KIWISAVER: RETIREMENT SECURITY, OR A PAY CUT WITH A HALO?

The policy asks workers to trade spending power today for financial security decades from now. Whether that’s a bargain depends on who’s making the sacrifice.

The argument for bigger compulsory KiwiSaver contributions is politically tidy: save more now, retire with more later. The bill is less tidy. It arrives in weekly pay packets, rent accounts, grocery shops and childcare invoices long before it appears as a comfortable balance at 65.

That trade-off is no longer theoretical. Budget 2025 changes mean default employee and employer KiwiSaver contribution rates rise to 3.5% from April 2026 and 4% from April 2028, while the government contribution has been cut from a maximum $521.43 a year to $260.72 and removed for people earning over $180,000.^[1] Inland Revenue says members can apply a temporary rate reduction to stay at 3% for between three and 12 months, but that is a pressure valve, not a magic money tree.^[2]

Other ideas are now circling the runway. National has promised to lift employee and employer default rates to 6% each by 2032, or 12% combined.^[3] New Zealand First has floated automatic KiwiSaver enrolment from birth with a $1,000 government seed payment, then compulsory contributions from 18 starting at 8% and rising to 10%, offset by tax cuts; RNZ reported an economist saying the package was not feasible.^[4] The Spinoff’s survey of party positions also records ACT’s opposition to further tax-funded contributions, Labour’s criticism of the Budget cut to the government contribution, Te Pāti Māori’s affordability concerns, and TOP’s support for a “KiwiSaver 2.0” model with higher matched contributions.^[5]

The present law is already partly compulsory. Employees aged 18 to 64 are automatically enrolled when they start a new job and can opt out during the provisional period.^[2] Employees can contribute 3.5%, 4%, 6%, 8% or 10% of before-tax pay, while employers must generally contribute at least 3.5%.^[6] The contributions are calculated on gross pay, but for workers the practical effect is brutally simple: more into KiwiSaver means less cash in the bank on payday.

For a worker earning $70,000, the move from 3% to 3.5% lifts employee contributions from about $40.38 a week to $47.11 — a weekly take-home cut of about $6.73.^[7] When the rate reaches 4%, the extra one percentage point compared with the old 3% default is about $13.46 a week. On $50,000, each extra one percentage point is $500 a year, or about $9.60 a week. On a full-time minimum-wage income of about $48,880, it is about $9.40 a week. That is lunch money in Wellington policy circles. In many households, it is the difference between paying the power bill on time and donating another fee to late-payment capitalism.

Employers also get a bill. Each additional percentage point of employer contribution is roughly 1% of payroll before employer superannuation contribution tax. A 10-person business paying workers $50,000 each faces about $5,000 more a year for every extra percentage point. In theory, that is paid on top of wages. In practice, the Retirement Commission found 45% of employers used “total remuneration” packages for at least some workers, meaning KiwiSaver can be counted inside the pay package rather than added on top.^[8] That is where the halo starts to flicker: if an employer contribution is absorbed into total pay, the worker funds the “employer” contribution too, just with nicer stationery.

Over time, even contributions genuinely paid by employers may still come back to workers through lower wage growth. Australian evidence is often cited because its compulsory superannuation system is much larger; the Grattan Institute concluded workers “overwhelmingly” pay for higher compulsory super through lower wages.^[9]New Zealand is not Australia, and the exact incidence here will depend on labour markets, bargaining power and enforcement. But pretending employer contributions are free is not analysis. It is advertising.

The hardship data should make politicians pause. Significant financial hardship withdrawals from KiwiSaver reached $471.2 million in the year to June 2025, up from about $300 million in 2024 and $104 million in 2019.^[10] NZ Herald reporting on Inland Revenue figures found 44,360 people withdrew $389.4m in just the first 10 months of 2024/25, compared with 32,480 people taking $300.5m in the full previous financial year.^[11] By law, hardship withdrawal is meant for people unable to meet minimum living expenses, mortgage or rent payments, medical costs and other serious needs.^[12]

That is the contradiction. The state is asking more people to lock away more money while a growing number are already begging to unlock it for survival. First-home withdrawals are also large: 43,600 people withdrew $1.86 billion for first homes in the year to June 2025.^[13] So higher contributions will not all become retirement income. Some will become housing deposits for those able to buy; some will later be pulled out under hardship by those who cannot.

The quiet winners are not hard to find. KiwiSaver assets passed $111.8b in the year to March 2024, with $11.2b in member, employer and Crown contributions flowing in that year.^[14] Morningstar data reported by interest.co.nz put assets at $121.9b by December 2024 and said the five largest providers held about two-thirds of the market.^[15] Fees follow assets. Interest.co.nz reported annual KiwiSaver fees pushing $1b, while the FMA reported about $790m in fees on $112b of assets in 2024.^[15][16] If policy pushes billions more through KiwiSaver each year, providers and fund managers collect a slice every year thereafter. That does not make them villains. It does mean they are beneficiaries, and beneficiaries of public policy deserve daylight.

The retirement-security case is real. About 3.4 million people are in KiwiSaver, but the Retirement Commission says roughly 39% of members are not contributing, often because of study, parenting, unemployment, retirement or other work interruptions.^[8] Average balances remain modest: $31,823 at the end of 2023, with 38% of members below $10,000.^[17] Men’s average balances were about 25% higher than women’s, and the Commission has warned Budget changes will hit low-income earners, Māori and women hardest unless gaps are addressed.^[17][18]

So the issue is not whether retirement poverty matters. It does. The issue is whether compulsory private saving is the fairest tool when the people most at risk are often those least able to contribute steadily. Higher earners get larger employer matches, larger balances and more compounding. Low-paid workers get a smaller pay packet now, and may still have interrupted contributions later.

A less punitive design would start by admitting that equal percentage contributions are not equal burdens. Options include stronger low-income government matching, carer credits, hardship exemptions that work before crisis point, banning total-remuneration clawbacks, fee caps, and employer-only increases backed by wage-protection rules. The Government could also choose more direct tools: higher wages, housing affordability, stronger NZ Super settings or targeted public retirement credits.

If politicians want more compulsory KiwiSaver, they should say the quiet part clearly: whose weekly cash shrinks, whose balance sheet grows, and why locking money away is better than letting households use it for rent, food, childcare and power today. Future security is a worthy goal. But rent is still due on Thursday.
