Koura Wealth founder Rupert Carlyon questions affordability of compulsory KiwiSaver

KiwiSaver providers have put affordability at the centre of National's new compulsory-savings proposal, with Koura Wealth founder Rupert Carlyon among those warning that higher mandatory contributions would need careful design if households are already stretched. National used its annual conference on Sunday to propose a wider KiwiSaver overhaul if it is re-elected: automatic enrolment for children at birth, a $1500 Baby Boost payment, compulsory participation for workers from mid-2028 and a combined employer and employee contribution rate that would rise to 12 percent by 2032. The policy is pitched as a long-term retirement-security measure, but the immediate question is how workers, employers and small businesses would absorb the change.

Carlyon's response matters because it comes from the founder of a KiwiSaver provider that works directly in the retirement-savings market. He welcomed the idea of getting children saving earlier and pointed to the value of compounding over time, but he also raised the practical problem that a bigger combined contribution rate has to come from somewhere. For employees paid through total remuneration packages, the line between employer contribution and take-home pay can be especially thin. A higher compulsory rate may look like a retirement gain on paper while still feeling like a pay cut in a household budget.

The policy would also land after several years in which KiwiSaver settings have already moved. Inland Revenue says minimum employee and employer rates lifted to 3.5 percent from 1 April 2026 for affected members, with further settings depending on age and eligibility. National's new plan would go much further by making the system universal for workers and pushing total contributions closer to Australian-style superannuation. That is a major structural shift for a country where KiwiSaver has historically mixed automatic enrolment for new employees with opt-out rights and voluntary settings.

The political appeal is clear. New Zealand faces a long-running argument about whether the current superannuation model is sustainable as the population ages. More private retirement saving could reduce future pressure on public finances and give younger workers a larger asset base by the time they retire. Starting children with a $1500 payment would also give families a visible account from the beginning of life, which may change how people think about long-term saving. Those are real benefits if contributions are maintained, fund fees are controlled and investment returns compound over decades.

The risk is that compulsion without enough flexibility can punish people at the wrong point in their financial life. A worker dealing with rent, mortgage stress, high-interest debt, childcare costs or irregular hours may need cashflow before locked-up savings. Small employers may also face higher wage costs if contribution increases are treated as additional to pay. If they are instead folded into total remuneration, the worker may carry more of the burden. The debate therefore cannot be reduced to whether saving is good. It is about timing, incentives, wage structures and whether low-income households are protected.

For business owners, payroll teams and financial advisers, the next test is detail. They will want to know how exemptions work, what happens to people with existing equivalent schemes, how self-employed workers are treated, whether hardship settings change and how compliance costs are managed. Carlyon's concern does not reject the retirement problem. It points to the implementation problem. A compulsory KiwiSaver system may be inevitable in some form, but the version that survives public scrutiny will need to show how today's workers can afford tomorrow's savings.
