The Waikato area is under a heavy rain watch today, with downpours of up to 40mm an hour possible at times.
Metservice has warned that until 7am on December 30, periods of heavy rain are possible across the Waikato, Waitomo, Taumarunui, Taupō, Tongariro National Park and Kaimanawa Mountains regions.
There may also be thunderstorms.
It’s one of several alerts in place for New Zealand today, with heavy rain warnings active for Mount Taranaki, Nelson and Westland, as well as watches for Bay of Plenty, Buller, Fiordland and the Richmond and Bryant Ranges.
The latest spell of bad weather for the area comes as MetService meteorologist Mmathapelo Makgabutlane warned the long weekend might see challenging some conditions.
