Key Takeaways
- A default contribution rate of 5 % + 5 % (employee + employer) is proposed to smooth lifetime consumption, especially for those with childcare or other pre‑retirement expenses.
- Some experts argue that moving to 6 % + 6 % could leave many retirees with more income or purchasing power after work than before, but this outcome depends heavily on individual circumstances.
- Higher‑income earners may still fall short of a replacement income even at 6 % + 6 % and are expected to seek private financial advice to supplement savings.
- Early withdrawals for a first home—particularly if taken from the 40s onward—require contributors to rebuild savings later, increasing the amount they must set aside.
- Setting default rates too high risks prompting more people to suspend KiwiSaver contributions altogether, undermining the scheme’s effectiveness.
- Economist Shamubeel Eaqub notes that the calculations assume NZ Super will remain unchanged; he believes a 12 % total contribution rate (matching Australia) is a reasonable baseline, though not universally ideal.
- Eaqub advocates openness to future changes to NZ Super, including possible means‑testing, to preserve the benefit for those who truly need it while maintaining fiscal sustainability.
- Rupert Carlyon of Koura warns that compulsory KiwiSaver could be a first step toward means‑testing NZ Super, questioning the honesty of politicians promoting compulsion.
- The National Party plans a combined 12 % rate by 2032, aligning New Zealand with Australia and Canada and presenting it as a minimum standard to improve retirement security for all workers.
The Rationale Behind a 5 % + 5 % Default Rate
The discussion centres on using a modest default contribution of five percent from employees and five percent from employers as a way to smooth consumption over a lifetime. Proponents argue that before retirement many people face expenses such as childcare, mortgage payments, or other family‑related costs. By setting a lower, predictable savings rate, individuals can maintain a more stable standard of living both while working and after they stop earning a wage.
Why Some Experts Favor a 6 % + 6 % Approach
Other voices in the debate suggest that raising the default to six percent each from employee and employer could leave retirees with greater income or consumption power after retirement than they had while working. This “overshoot” would act as a buffer against longevity risk and unexpected costs in old age. However, the commentators caution that this outcome is not guaranteed and hinges on personal factors such as earnings trajectory, lifespan, and spending habits.
Influence of Individual Circumstances on Savings Adequacy
The analysis stresses that individual circumstances play a decisive role in whether any given contribution rate will meet retirement needs. For example, someone with a stable, high‑earning career might still fall short of a replacement income even at 6 % + 6 %, while a lower‑earner with fewer pre‑retirement obligations could be comfortably covered by the 5 % + 5 % baseline. Consequently, policymakers are urged to allow flexibility so that people can adjust contributions according to their unique situations.
Higher Earners and the Need for Private Advice
Higher‑income individuals are noted as a group that may not achieve adequate replacement income solely through compulsory KiwiSaver, even at the elevated 6 % + 6 % level. Because they typically have greater access to financial resources, the expectation is that they will seek professional financial advice or make additional voluntary savings to bridge any gap. This reliance on private planning underscores the limits of a one‑size‑fits‑all compulsory scheme.
Impact of Early Withdrawals for a First Home
A significant consideration is the effect of withdrawing KiwiSaver funds for a first‑home purchase. If such a withdrawal occurs during a person’s 40s or later, the individual must re‑accumulate the depleted balance to maintain adequate retirement reserves. This “re‑building” phase can substantially increase the total amount a person needs to save over their working life, suggesting that policies around home‑ownership withdrawals should be coordinated with retirement‑saving goals.
Risks of Setting Default Rates Too High
Experts warn that excessively high default contribution rates could backfire by prompting more participants to suspend or opt out of KiwiSaver altogether. When compulsory savings feel overly burdensome, especially for those with tight budgets or irregular income, the net effect may be a reduction in overall retirement coverage rather than an increase. Therefore, any adjustment to the default rate must weigh the desire for higher savings against the risk of disengagement.
Shamubeel Eaqub’s View on NZ Super and the 12 % Benchmark
Shamubeel Eaqub, chief economist at Simplicity, points out that much of the modelling assumes NZ Super will remain unchanged in its current form. He argues that a total contribution rate of around 12 %—matching the rates in Australia and moving toward Canada’s level—provides a sensible starting point. While acknowledging that no single policy fits every individual in a nation of 5.5 million, Eaqub believes the 12 % target is good enough as a universal floor, provided it is reviewed periodically.
Openness to Future Changes in NZ Super
Eaqub also urges policymakers to remain open to modifications of NZ Super, including the possibility of means‑testing. He contends that means‑testing would be the fairest way to preserve the benefit for those who truly need it while ensuring the program’s long‑term fiscal sustainability. Compulsion in KiwiSaver, he suggests, could be the first step toward such a reform, signalling a broader shift in how New Zealand finances retirement income for its ageing population.
Rupert Carlyon’s Critique of Compulsory KiwiSaver as a Stepping Stone
Rupert Carlyon, founder of Koura, challenges the narrative that compulsory KiwiSaver is solely about boosting retirement savings. He posits that the real motive may be the initial phase of means‑testing NZ Super, arguing that if the universal pension were not slated for reduction or restructuring, there would be less justification for enforcing higher contribution rates. Carlyon calls for greater transparency from politicians about whether compulsion is a prelude to altering the superannuation system.
National Party’s Policy Alignment with Australia and Canada
The National Party’s stance is presented as a plan to increase the combined KiwiSaver contribution rate to 12 % by 2032, explicitly aiming to bring New Zealand in line with the retirement‑saving frameworks of Australia and Canada. A party spokesperson describes this as establishing a minimum standard that guarantees every working New Zealander a baseline level of retirement savings, thereby enhancing overall financial security in later life. The policy is framed as a pragmatic response to longevity risk and the desire to avoid old‑age poverty, while still recognising that personal circumstances will dictate whether additional voluntary saving is advisable.
