Reserve Bank Review Hands Willis Mandate Defence, Reopens Coalition Faultline
Finance Minister Nicola Willis has used the independent review of the Reserve Bank's Covid-era monetary policy to defend the Government's decision to return the bank to a single mandate.
The review was undertaken by MIT Professor Athanasios Orphanides and former Reserve Bank Assistant Governor David Archer. It found the Bank's initial Covid response was appropriate but that monetary stimulus remained in place too long. It stated that increased flexibility in monetary policy facilitated large policy mistakes during the period under review. RNZ
Willis said the review welcomes the return to a single mandate. The argument is familiar in the Beehive. A tight focus on price stability reduces discretion. Less discretion means smaller errors.
The mandate history is not contested. In 2018, the previous Government expanded the remit to require support for maximum sustainable employment alongside price stability. After taking office in 2023, the Government reverted the Bank to a single mandate in the first bill it passed. Legislation passed on 13 December 2023. Willis said at the time the Government had met its 100-Day commitment to return the Bank to a single focus on inflation. Beehive
Labour leader Chris Hipkins defended the dual mandate. He said it works well in other countries and that keeping people in work is an important priority. Labour's fiscal strategy released in August contained a commitment to bring back the dual mandate.
New Zealand First has also signalled it wants to bring back the dual mandate. That is notable. The party supported the Government's legislation returning the Bank to a single mandate. It now favours reversing that position.
The debate is running alongside a live tightening cycle. On 2 September 2026, the Monetary Policy Committee agreed to increase the Official Cash Rate by 25 basis points to 2.75%. Reserve Bank
Committee process is also changing. In April 2026, New Zealand moved to make Monetary Policy Committee votes public. Willis said changes to Committee arrangements will ease existing restrictions, allowing 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.
The review architecture sits behind the current argument. The RAFIMP review was published before the 2023 amendment to Reserve Bank legislation took effect. It covered the period during which the Committee operated under a dual mandate. The Bank also published a document titled '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. For those who work the Press Gallery and select committee corridors, the lines are now clear. The Government holds the single mandate as settled policy validated by Orphanides and Archer. Labour has locked in reversal in its fiscal strategy. New Zealand First is positioning for reversal while still bound to the statute it voted for. With the OCR moving up again and individual votes soon to be on the record, every MPC decision will be read for mandate implications. The politics are sharp. The economics will be tested meeting by meeting.
