Falling global crude oil prices have ensured tradables inflation has continued to decline and in the first quarter that measure dropped 0.9 percent. Non-tradables inflation, which reflects those goods and services that don't face foreign competition and shows how domestic demand and supply conditions are affecting consumer prices, rose 1 percent.
In the year, the tradables component fell 1.2 percent and non-tradables rose 1.6 percent.
The Reserve Bank next updates its forecasts in the monetary policy statement on June 9.
In a recent speech, Deputy Governor Geoff Bascand said much of the weakness in inflation could be attributed to falling commodity prices and a high New Zealand dollar. But he also pointed to higher productive capacity "from rapid growth in the labour force" which was keeping a lid on wage inflation as the economy grew.
Supply and demand in the labour market had been "broadly in balance since early 2014, creating little upward pressure on wages," Bascand said.
Fruit prices contributed 0.09 percentage points to quarterly inflation, while rentals for housing added 0.06 points and purchases of newly built homes added 0.04 points.
After petrol, the biggest downward pressures came from international air fares, taking away 0.27 percentage points, package holidays, down 0.09 points and domestic airfares, down 0.03 points.
The so-called trimmed mean, which excludes extreme price movements, fell 0.2 percent in the year, including cigarettes and tobacco, but rose 0.7 percent excluding petrol. Excluding housing and household utilities, the annual CPI declined 0.4 percent.
