New rules aim to align with global best practice
The Reserve Bank of New Zealand (RBNZ) and the Minister of Finance have agreed on changes to the Monetary Policy Committee (MPC) Charter, which took effect on Thursday, aimed at strengthening transparency and accountability in monetary policy decision-making.
The updated Charter, signed by RBNZ Governor Anna Breman on Tuesday and minister of finance Nicola Willis on Wednesday, introduces attributed voting records and encourages MPC members to publicly communicate their individual views on the economic outlook and monetary policy strategy. The changes take effect beginning with the May 2026 Monetary Policy Statement.
Named voting and dissent disclosures introduced
Among the key changes, individual votes cast during MPC meetings will now be attributed to specific members, rather than recorded collectively. Beyond votes, the MPC also intends to attribute material differences of view or judgement among committee members in the published Record of Meeting – even when the committee reaches consensus on a decision.
The Charter also reconfirms that the MPC’s decision-making process should continue to seek consensus where possible, with a simple majority vote serving as a fallback when consensus cannot be reached.
“These changes make it easier for MPC members to communicate their individual views and brings us in line with some of the most transparent central banks in the world,” Breman said.
Breman, who began her role as governor in December, has pushed for a more open central bank since taking office. The significance of the timing is underscored by the MPC’s most recent decision: on April 8, the committee reached consensus to hold the Official Cash Rate (OCR) at 2.25%, with some members placing more emphasis on arguments for an early monetary policy response while others pointed to downside risks to growth amid Middle East conflict disruptions.
Under the new Charter, such differences of view would now be attributed in the published record.
Communication guidelines tightened for members
The Charter also retains existing rules ensuring equal access to information among members.
Any MPC member who wishes to publicly communicate material new information about monetary policy strategy must provide advance notice on the Reserve Bank’s website, with prepared remarks published alongside their release elsewhere.
Members must also refrain from any public communications relevant to monetary policy after receiving MPC briefing papers and before a decision is announced.
“Monetary policy transparency is important as it ensures that central banks remain accountable to the public and credible in their decisions. The changes to the Charter further enhance the transparency of monetary policy decision-making at the Reserve Bank of New Zealand,” Breman said.
Breman said the Charter update is part of a broader effort that already includes the introduction of press conferences at Monetary Policy Reviews, an increase to eight monetary policy meetings per year, and expanded public outreach.
“There will be a 12-month review of the Charter to ensure that the changes are having a positive impact on the understanding of MPC decision-making, publicising of individual members’ views and overall monetary policy transmission,” Breman said.
