The MPC is responsible for the monetary policy decisions needed to support price stability.
Ms Williams, Senior Manager Economics, starts a 1-year term on 15 October 2026. Ms Williams fills a seat on the Committee that has been vacant since March 2025 and ensures continuity of internal membership following Karen Silk's departure.
"We are delighted to welcome Rebecca to the MPC. She has worked extensively in monetary policy and forecasting, including advising the MPC on the current state of the New Zealand economy," RBNZ Chair Rodger Finlay says.
"Rebecca brings a strong understanding of the monetary policy settings required to meet the Bank's inflation objective."
Ms Williams joined RBNZ in 2010 and has a BCom (Hons) in Economics and a BA in History from the University of Canterbury.
"We look forward to working with Rebecca, whose many years of experience in economic analysis and forecasting, including leadership of analysts, will be a real asset to the Committee," RBNZ Governor and MPC Chair Dr Anna Breman says.
"With her analytical capabilities alongside deep institutional knowledge, I know Rebecca will make a significant contribution to our work."
Ms Williams will take part in the Monetary Policy Review being delivered on 28 October 2026.
