ASB Bank expects the consumers price index (CPI) to remain unchanged for the December 2012 quarter, compared with a 0.3 per cent rise in the September quarter.
The ASB's forecast compares with a Reserve Bank forecast of a 0.1 per cent quarterly increase. The median of market forecasts is also for a 0.1 per cent increase over the quarter.
An unchanged quarterly CPI will bring the annual rate of inflation up to 1.1 per cent from 0.8 per cent in the year to September, which means annual inflation will move back inside the Reserve Bank's 1 to 3 per cent inflation target band, ASB said.
December is a seasonally weak quarter for inflation, largely due to the seasonal decline in fruit and vegetable prices heading into summer.
Food items make up 19 per cent of the CPI basket, and as a result food prices tend to have a large impact on the quarter-to-quarter movements in inflation.
