Motorists are being asked to take care when crossing the harbour bridge this evening and tomorrow as severe gusts batter Auckland.
A front preceded by moist easterlies moved onto New Zealand earlier today, Met Service said.
The easterlies, which will be at their worst in exposed places like the harbour bridge, may reach 90km/h.
This has triggered NZTA to keep the Auckland Harbour bridge at a four-by-four configuration for most of Wednesday and all of Thursday.
