New Zealand's farm and forestry exports are bouncing back in the wake of the global recession, agricultural economists say.

Sheep numbers have continued to fall, dairy cow numbers are rising and grain crops increased markedly, latest agricultural production figures show.

Carter Holt Harvey is putting 29 dairy farms on the market, asking $224.5 million in the biggest single offering of farm land seen in NZ.

A report by three top climate think-tanks says efforts planned by NZ to cut greenhouse gases stack up better than the EU's.

Rising dairy prices continue to underpin gains in the ANZ Commodity Price Index, which has recorded its seventh straight monthly gain last month.
