Weather: Warnings in place as rain soaks country

It's a good night to sit inside with a hot chocolate and a fire, as severe weather batters the country.

A series of fronts tracking over the country are set to bring heavy rain, thunder, snow and hail across New Zealand on Sunday night.

More than 100 lightning strikes hit Auckland within an hour, and travellers are warned to keep an eye on flights in case of weather-induced delays or cancellations.

A heavy rain watch is in place for Kapiti, Wellington, Marlborough and Canterbury, with a thunderstorm watch also in place for the northwest coast of the North Island.

The rain is expected to continue through the night and into Monday morning, with the Canterbury and Marlborough regions set to soak through into the afternoon, according to MetService.

Another dose of wet weather is predicted to hammer the country on Monday - not that you'd notice anything was wrong if you were in Prime Minister Bill English's Auckland.

He tweeted an image of himself and his wife enjoying a lovely beach walk on Monday night, captioning it: "A beautiful evening for a walk on the beach!"

At the same time, Auckland was being battered by pouring rains and lightning strikes. NIWA shared an image of the moment lightning struck the Sky Tower, lighting up the sky as bright as day.
