The "Couples Rate" vs. The "Single Rate"

A frequent source of frustration for new retirees is why the first person in a couple to turn 65 receives a reduced pension rate. Currently, an individual living alone receives $1,294.74 per fortnight (before tax), whereas a person in a relationship receives the "sharing" rate of $984.28. The Ministry of Social Development (MSD) maintains that the system is designed around the reality of shared household expenses. Even if one partner is under 65 and ineligible for NZ Super, the eligible partner is still moved to the lower rate because they are presumed to have the financial support of a partner.

Actuarial Assumptions in Retirement Calculators

Critics have questioned the Sorted KiwiSaver calculator’s use of a 3.5 percent annual income growth assumption, with some users calling it "wildly out-of-date" in the current economic climate. However, Sorted’s personal finance lead, Tom Hartmann, defends the figure as an actuarial standard. While wage growth is rarely linear, the 3.5 percent figure accounts for career progression, job changes, and long-term economic cycles. Over the last decade, New Zealand's average wage growth actually sat closer to 4 percent, though this data is skewed by recent high-inflation periods.

Flexibility for Post-65 KiwiSaver Members

For those over the age of 65, the rules regarding KiwiSaver change dramatically. As noted in the case of a nurse on casual contracts, there are no longer restrictions on withdrawing funds. Financial experts suggest that if an individual needs immediate liquidity—such as moving funds into a term deposit—they can do so while keeping the KiwiSaver account open for future employer contributions. The strategic rationale remains the same: align the investment with the timeline of need. Long-term funds should remain in growth assets, while immediate cash needs are best served by low-risk bank deposits.
