Excluding petrol and tobacco products, annual CPI rose by a smaller 1.5%.
Why does the government have to track food and other prices in such a granular way?
The cost of living is rising at the fastest rate in more than five years, with inflation jumping on the back of higher food and fuel prices.
Official numbers show inflation of 1 percent for the three months ended March, pushing the annual rate to 2.2 percent, the highest since mid-2011.
A better than expected CPI reading out of New Zealand triggered a surge higher in NZD/USD in early trading but gains were not sustained as sharp fall in early European trading served to erase most of the early day gain.

Housing-related prices were up 3.3 percent, while transport prices rose 3.5 percent.
Cheap oil in recent years and the tepid inflation environment has made life hard for New Zealand's Reserve Bank, which delayed cutting interest rates too aggressively for fear of stoking demand for an already hot property market. In New Zealand, the Consumer Price Index or CPI measures changes in the prices paid by consumers for a basket of goods and services.
- Annual inflation in March 2.2%, quarterly inflation 1%.

Inflation in the quarter rose 1%, ahead of the Reserve Bank's forecast of 0.4% and the market expectations of 0.8%.
