Core conclusion · Tlines extraction
Westpac NZ argues higher fuel costs, a weaker NZD and a soft housing market have shifted the near-term outlook. Annual CPI is expected to dip to 3.7% in September before rising to a three-year high of 4.2% by December, half a point above Westpac's prior projection and above the RBNZ's 3.9%. The OCR call is unchanged: a pause at the October review, then a 25bp hike to 3% in December. 2026 house price growth is now forecast at -1.4% versus +0.6% previously.

Key arguments
- Global fuel prices amplified by a more than 4% NZD fall since early September pushed local 91 unleaded to a record $3.60/litre and roughly 50 cents higher over the month.
- Westpac expects December quarter prices to rise 1.1%, lifting annual inflation to a three-year high of 4.2%, above the RBNZ's September forecast of 3.9%.
- Despite the inflation spike, Westpac holds its OCR call: pause in October, then +25bp to 3% at the December Monetary Policy Statement.
- Housing has failed to stabilise: weakening sales, a 48-day median selling time, soft labour market, higher mortgage rates and more listings drive the 2026 price forecast to -1.4%.
Key numbers
- Annual CPI, December 2026 forecast
- 4.2%
- Annual CPI, September 2026 forecast
- 3.7%
- RBNZ September CPI forecast
- 3.9%
- Forecast 2026 national house price growth
- -1.4%
- Median days to sell a property
- 48 days
Main risks
- Any easing in annual inflation is likely to prove short-lived, with the higher year-end starting point keeping inflation firm through much of 2027.
- Further NZD downside is possible but likely limited; a break below 0.5580 support would open a move toward the decade low of 0.5490.
- Housing headwinds could persist given soft labour demand, elevated mortgage rates and rising listings, destabilising the consumption outlook.
Corresponding source evidence
Inflation looks set to finish 2026 above 4%, while growth could lose a little momentum into year- end.
· 2026Even so, we continue to expect the RBNZ to pause in October before lifting the OCR to 3% in December.
Since our last forecast update in August, global oil and refined-fuel prices have climbed sharply, the New Zealand dollar has fallen, and longer-term interest rates have moved higher.
