Reserve Bank review reignites single vs dual mandate debate
Finance Minister Nicola Willis says an independent review of the Reserve Bank's Covid-era policy supports the Government's decision to return the Bank to a single mandate.
The review was done by MIT Professor Athanasios Orphanides and former Reserve Bank Assistant Governor David Archer. It said the Bank's first response to Covid was appropriate, but extra stimulus stayed in place for too long. It said increased flexibility in policy allowed large mistakes during that period. RNZ
Willis said the review welcomes the return to a single mandate. The argument, often made in the Beehive, is that a tight focus on price stability leaves less room for judgement calls. Less room means smaller errors.
The history is not disputed. In 2018, the previous Government expanded the remit to require support for maximum sustainable employment alongside price stability. After the 2023 election, the new Government removed that second goal in the first bill it passed. The legislation was passed on 13 December 2023. Willis said at the time the Government had met its 100-Day commitment to refocus the Bank on inflation. Beehive
Labour leader Chris Hipkins defended the dual mandate. He said it works well in other countries and keeping people in work is an important priority. Labour's fiscal strategy, released in August, commits to bringing the dual mandate back.
New Zealand First has also said it wants to bring back the dual mandate. The party voted for the Government's legislation to return to a single mandate. It now favours reversing that law.
The debate is happening while rates are tightening again. On 2 September 2026, the Monetary Policy Committee, the group that sets interest rates, lifted the Official Cash Rate by 25 basis points, or 0.25 percentage points, to 2.75%. Reserve Bank
How the Committee works is also changing. In April 2026, New Zealand moved to make each member's vote public. Willis said the changes will ease existing restrictions and give members more freedom to discuss monetary policy. Reuters
Governor Anna Breman was in place in April 2026. She said then she still expected New Zealand's economy to grow in 2026.
On timing, the RAFIMP review was published before the 2023 amendment to Reserve Bank legislation took effect. It covered the period when the Committee operated under a dual mandate. The Bank also published a document called 'In Retrospect: Monetary Policy in New Zealand 2017-22'.
The broader context here is about credibility, flexibility and coalition arithmetic rather than Covid history alone. The Government treats the single mandate as settled policy backed by Orphanides and Archer. Labour has locked reversal into its fiscal strategy. New Zealand First is positioning for reversal while still bound to the law it voted for. With the OCR moving up again and individual votes soon on the record, each meeting will be read for what it says about the mandate.
