New data shows New Zealanders contributed a record $11.1bn to KiwiSaver in the year to March — yet the industry delivered just 1.9% in net returns. In the March quarter alone, members added $2.7bn but fund managers lost $3.5bn in market value.
New Zealanders contributed a record $11.1 billion to their KiwiSaver accounts in the year to March 2026, according to IRD data cited by interest.co.nz — but the investment returns delivered by fund managers over the same period were underwhelming. The industry's net performance for the year came in at just 1.9 percent, according to Reserve Bank data on KiwiSaver assets by sector.
The figures emerged in RBNZ data on KiwiSaver assets by sector, which showed that while members were adding money steadily, the funds themselves lost ground in certain periods. In the March quarter alone — spanning January to March — members contributed $2.7 billion across employee, employer, and Government contributions. But the value of KiwiSaver assets actually fell by $650 million over the same period, implying fund managers lost approximately $3.5 billion in market value in that quarter.
The contrast between contributions and returns is significant. Workers funneling money into KiwiSaver each payday are expecting long-term growth. When investment markets are volatile — as they were through 2025 and early 2026 — the gap between what goes in and what the fund is worth at any point in time can be material.
How KiwiSaver returns work
KiwiSaver is designed as a long-term investment. Members' balances reflect both what they contribute and how the underlying investments perform. When markets fall, the value of existing holdings drops even if no withdrawals are made. The RBNZ data for the year to March shows the total value of KiwiSaver assets rose by $13.5 billion — but that includes the $11.1 billion in member contributions. Strip those out and the net investment gain was only around $2.4 billion, or roughly 1.9 percent of the total pool.
Interest.co.nz noted that fund managers collectively earned an estimated $900 million in management fees over that same period — a figure that underscores the cost structure of the industry regardless of investment outcomes.
What the surveys show
Consumer sentiment data from the May ANZ-Roy Morgan survey showed households remained deeply cautious about their finances. The net proportion of people thinking it's a good time to buy a major household item sat at negative 20 — still very low, though improved slightly from April. Inflation expectations two years ahead eased to 5.3 percent from 6.6 percent, which may provide some relief to funds that hold fixed-income investments.
For KiwiSaver members, the practical takeaway is that short-term return figures can be misleading in context. A year that ends with a 1.9 percent gain is still a gain — and the Government-matched contribution means every dollar contributed earns a 50 cent top-up. But the gap between contribution flows and fund performance in the March quarter is a reminder that investment returns and cash contributions don't move in lockstep.
