Traders have priced in an outside chance New Zealand's Reserve Bank governor Graeme Wheeler will cut the official cash rate by 50 basis points on Thursday in response to a sagging dairy sector and low inflationary expectations.
Minutes to the RBA's July 7 meeting show the board expected more assistance to hits inflation target from a weaker Australian dollar and traders have priced in a 24 percent chance Australia's central bank will reduce rates next month.
"We saw a mild increase in the easing bias by the RBA and that encouraged traders to keep pressure on the Aussie dollar," said ANZ's Sam Tuck.
"The market sees the window of opportunity for the RBNZ to have an immediate impact on the New Zealand dollar as closing. You'd really need to see a 50 [basis point cut] to send the New Zealand dollar lower."

New Zealand net migration reached a new record in June, and is nearing the Treasury's topside forecast, which would fuel consumer spending and add pressure to the housing market, while short-term arrivals continued to rise.
