The bank also increased its three-year fixed terms by 6bps to 5.35% (special) and 5.95% (standard).
The Reserve Bank (RBNZ) is due to make its next Official Cash Rate (OCR) decision on Wednesday, May 27.
The OCR currently sits at 2.25%, where it has been since November last year.
Higher-than-expected inflation figures have lifted the odds of the first OCR hike coming in May.
New Zealand’s Consumers Price Index (CPI) increased 3.1% in the 12 months to the March 2026 quarter, according to Stats NZ.
That’s above the RBNZ’s target band of 1-3%.
Market pricing now points to a 40% chance of a 25bps rate hike in May, up from a 20% before the CPI’s release.
