World prices for a basket of New Zealand's export commodities flattened out last month as declining prices for dairy products offset widespread gains elsewhere.
ANZ's commodity price index fell 0.1 per cent from February's level, which was a record high in the index's 28-year history. It is still 13.8 per cent above its level a year ago and nearly twice as high as in the recession's depths five years ago.
Converted into New Zealand dollars, the commodity index dropped 2.6 per cent last month, reflecting a strong rise in the exchange rate.
"Nevertheless the level of commodity prices valued in New Zealand dollars remains elevated, up 12 per cent on a year ago, and is just 6 per cent below its March 2011 peak," ANZ economist Steve Edwards said.
Ten of the 17 commodities in the index rose in March, led by a 9 per cent rise in sheepmeat to a two-year high., driven by demand from China and the Middle East, Edwards said.
