The food price index fell a seasonally adjusted 0.8 per cent in June, adding to the 0.1 per cent dip in May and a 0.5 per cent decline in April.
The government agency adopted seasonal adjustment for the series for the first time, which aims to smooth the impact of seasonal events such as annual fruit and vegetable cycles. Food prices fell 0.1 per cent on an annual basis.
On an unadjusted basis, food prices rose 0.5 per cent in June, reflecting the impact of winter on vegetable prices.
"Higher food prices in June were influenced by seasonally higher prices for fresh fruit and vegetables," consumers price index delivery manager Matt Haigh said in a statement.
"However, food prices fell 0.8 per cent this month after adjusting for seasonal increases for items such as tomatoes and lettuce."
Food prices account for about a fifth of the broader CPI, which dropped below the Reserve Bank's 1 per cent to 3 per cent target range, rising at an annual pace of 0.1 per cent in the year to March 31.
Statistics NZ will publish second-quarter inflation data later this week, which the central bank expects will show consumers prices rose at a 0.3 per cent annual pace.
