The New Zealand dollar fell along with other currencies linked to commodities on concern Chinese demand is waning.
The kiwi dropped to 67.65 US cents at 8am in Wellington, from 68.43 cents at 5pm on Monday.
The trade-weighted index declined to 72.34 from 72.79, while the US dollar index advanced to 94.157 from 93.815.
Investors shunned currencies of commodity producing countries such as Australia and New Zealand as their appetite waned for higher risk assets linked to global growth.
The CRB Index, which measures a basket of 19 global commodities, touched its lowest level in more than two weeks after Chinese trade data at the weekend showed exports and imports fell more than expected in April.
It stoked concern about weak domestic and international demand.
"Across the board, commodity weakness and dollar strength prevailed," said OMF's Stuart Ive. "The New Zealand dollar joined and led the commodity currency rout."
He said expectations that New Zealand's Reserve Bank will follow Australia and cut interest rates further is also weighing on the kiwi.
In New Zealand, the government's financial statements for the nine months through March are released, along with April electronic card spending and the latest monthly ANZ inflation gauge.
Traders will be eyeing Chinese inflation and producer prices data for April as they assess the outlook for demand in New Zealand's largest export destination.
