What will the next RBNZ decision mean for your mortgage?
The state of New Zealand’s economy right now
Before we can guess what the RBNZ will do next, we need to know what the economy is like right now. Here’s where things currently stand:
- Inflation: The RBNZ’s main goal is to keep prices stable, which means keeping inflation between 1% and 3%. Inflation has been running hotter than expected through 2026, largely due to the Middle East conflict pushing up global oil and fuel prices. Annual inflation sat at 3.1% in the March 2026 quarter and has since climbed further, with some forecasts putting the peak near 4%. The RBNZ expects inflation to gradually ease back toward its 2% target over the next 12 months as fuel-related price pressure drops out of the annual numbers. For a full breakdown of how rising costs are affecting everyday spending, see our guide on dealing with New Zealand’s rising cost of living.
- Economic Growth: The RBNZ needs to find a balance between fighting inflation and supporting economic activity. Weaker consumption and investment have slowed the pace of recovery in 2026, and the bank continues to watch GDP numbers, unemployment rates, and business confidence closely to avoid tightening more than necessary.
- Things that happen around the world: The economy of New Zealand doesn’t work in a vacuum. The Middle East conflict has been the single biggest global factor shaping RBNZ decisions this year, driving up fuel and shipping costs and forcing the bank to reassess its rate path mid-cycle. When the RBNZ decides what to do with interest rates, it weighs these global shocks alongside domestic conditions.
After cutting the OCR through late 2025 to a low of 2.25%, the RBNZ raised the rate to 2.50% in July 2026 — its first hike in three years — in response to this inflation pressure. The next scheduled decision is a Monetary Policy Statement on September 2, 2026, which will show how much further, if at all, the RBNZ thinks it needs to go. For more on how the OCR cycle has moved through 2026, see what the OCR cut means for 2026.
Possible Outcomes for the Next OCR Announcement
Going into the September decision, the RBNZ can hold the OCR at 2.50%, raise it further, or begin cutting again. Each option would send a different message to the market and have different effects on people with mortgages.
Scenario 1: The RBNZ Holds the OCR
A decision to hold would suggest the RBNZ believes 2.50% is currently doing enough to bring inflation back toward target without further tightening. This is the outcome most analysts currently see as likely, given that recent hikes haven’t fully flowed through to the economy yet.
- Immediate Effect: If rates stay the same, floating mortgage rates likely won’t change much right away. Banks may still adjust fixed-rate offers based on their own funding costs and forward expectations.
Scenario 2: The RBNZ Raises the OCR Again
A further hike would signal the RBNZ is still concerned inflation isn’t cooling fast enough, particularly if fuel and import costs stay elevated.
- Immediate Effect: Banks would almost certainly pass on the increase to customers with floating or variable-rate mortgages, and new fixed-rate pricing would likely rise too.
Scenario 3: The RBNZ Starts Cutting Again
A cut would mean the RBNZ is confident inflation is back under control and is shifting focus to supporting growth. Given inflation is still running above target, this is the least likely near-term outcome, but remains the direction most forecasters expect once inflation clearly returns to the 2% midpoint.
- Immediate Effect: A cut would lower rates on floating mortgages, and banks might lower fixed rates in anticipation of further easing ahead.
