The market has been dialling back expectations that Wheeler will begin hiking faster than the central bank's track for the official cash rate implies in the face of economic data suggesting some steam may be coming out of the local economy.
"The market has lost some faith that the RBNZ will be ready to hike this year," said Jason Wong, currency strategist at Bank of New Zealand.
The central bank statement "ought to be a non-event, with the bank likely unwilling to drop its neutral policy stance despite most folk outside the bank believing overwhelmingly that the next move is much more likely to be a hike than a cut."
The kiwi dollar rose to 56.52 British pence from 56.36 pence late yesterday. It earlier reached as high as 56.74 pence as reports began to emerge of what British police are calling a terror attack after a car ploughed into pedestrians in London, killing four and injuring 20, while in a second attack a policeman was stabbed near the British parliament.
