A weaker dollar's helping commodity prices.  

ANZ’s Commodity Price Index hit a record high in March, rising 6.4% as the dollar weakened 2.8%. 

Global prices rose 4.1% – the second-highest monthly rise on record. 

BusinessNZ CEO Katherine Rich told Mike Hosking on the surface, higher prices look positive for exporters, but they're also facing much higher costs.  

She says the weaker dollar boosts export return but also makes imports more expensive.
