New IRD data shows $11.1 billion in KiwiSaver contributions flowed to fund managers over the year to March — a new record. But the return figures for many funds have been modest, raising questions about whether the volume of flows is matching quality of outcomes.
KiwiSaver contributions hit a new record high in the year to March 2026, with $11.1 billion flowing to fund managers across employee deductions, employer contributions, and Crown payments, according to data from IRD. The quarterly figure was $2.7 billion, broken down as $1.75 billion in employee deductions, $960 million from employers, and a small amount from the Crown.
The contribution mechanics
KiwiSaver contributions are collected by IRD and passed on to the scheme providers. Employee contributions are 3 percent of salary by default (though people can opt for 3, 4, or 8 percent), and employers must match at the same rate. The Crown contributes $10.92 per week for members earning under a threshold — a nominal amount that is more symbolic than substantive.
The $11.1 billion annual figure is a gross flow number. It does not account for people who withdraw their savings — for first home purchases, retirement, or financial hardship — or for those who switch schemes. The net growth in total KiwiSaver assets will be lower than $11.1 billion as a result.
The return question
The interest.co.nz commentary on the data pointed out a tension that is worth noting: the record flows are accompanied by what it described as "pretty average returns by many" fund managers. According to Sorted's Smart Investor tool, the best conservative fund returned 2.3 percent, the best balanced fund returned 3.8 percent, and the best growth fund returned a figure that the article leaves implied but not stated.
These are not impressive returns relative to the risk taken, particularly in a year when fixed term deposit rates were moving toward 4-5 percent. A conservative KiwiSaver fund should be competing with cash alternatives; if the risk-adjusted return is below what a term deposit offers, the fee drag is doing real damage to savers who are paying management fees on a fund that is delivering below the return available on a cash term deposit.
Who is actually getting good outcomes
The people most likely to be benefiting from KiwiSaver are those in higher-risk, higher-return funds who stayed invested through the volatility of 2022-2023 and have seen their balances recover. Those who switched to conservative funds after the downturn locked in losses and have had limited recovery since.
The people least likely to be benefiting are those in default schemes — many of which have been shown to have above-average fees and below-median returns — and who have never reviewed whether their scheme choice is appropriate for their age and risk tolerance.
What the record contribution number means practically
$11.1 billion per year flowing into KiwiSaver is substantial in the context of New Zealand's pool of investable assets. It represents a meaningful proportion of domestic managed fund flows and gives KiwiSaver significant weight as an institutional investor in New Zealand markets.
For the individuals contributing, the record flows are neutral as a signal. What matters is the net return after fees, the appropriateness of the scheme for their life stage, and whether they are paying attention to what they are invested in. Record inflows during a period of modest returns is not unambiguously good news — it can also mean people are paying fees on underperforming investments without noticing.
