The weather system that brought downpours to Canterbury overnight is travelling up the island and towards Wellington.
Heavy rain and strong wind watches remain place for parts of Canterbury north of the Rakaia River and the Kaikōura coast to Seddon until 11am.
MetService said rain caused surface flooding on some southern slopes of Banks Peninsula, but started to ease about 3.30am on Wednesday.
Nearly 100mm of rain fell in Banks Peninsula over 12 hours.
MetService said the rainband was moving northwards towards Kaikōura and Marlborough. While it appeared to be easing, it could still bring heavy downpours to Wellington on Wednesday morning.
Fire and Emergency had received three reports of tree branches falling in Christchurch and Diamond Harbour. However, they were minor and would be referred to the council.
