Bream Head to Cape Colville, Hauraki Gulf, Waitematā Harbour, Manukau Harbour

A ridge persists over the North Island today and tomorrow, while weakening fronts are affecting the South Island. Another front, which is followed by a change to strong southwesterlies, brings areas of rain to the southern and eastern South Island on Thursday. Meanwhile, a weak ridge of high pressure persists over the North Island, keeping a subtropical low pressure system to the northeast of the North Island at arm's length. A strong southwesterly flow spreads northwards over New Zealand on Friday, then weakens on Saturday as the high moves onto the country from the Tasman Sea.
