And on the coast, State Highway 1 from Timaru to Oamaru has reopened after being closed by flooding. There is water along the route and motorists are urged to drive to the conditions.
The Transport Agency has told drivers to be careful of the challenging conditions that remain in several parts of the country.
Peter Little from Met Service said there is a severe thunderstorm watch for parts of the North Island, and coastal gale warnings.
"For the North Island we have an unstable north-westerly flow that's bringing heavy showers with thunderstorms. That thunderstom risk extends right down all western areas of the North Island and also the north-west region of the South Island.
"For much of Canterbury and Otago where there was very heavy rain yesterday and snow that is now easing."
Bands of thunderstorms are affecting parts of the North Island. Over the past 24 hours our lightning detection network has recorded over 7300 strikes in the New Zealand region, with around 1600 over land https://t.co/BZWb7ZPiRd ^PL pic.twitter.com/etgQsCkAXO— MetService (@MetService) August 10, 2019
