"A few of these thunderstorms have been identified as severe and warnings have been issued for torrential rain, large hail, damaging wind gusts and possible tornadoes," it warns.
"The threat of squally thunderstorms remains over much of the North Island and upper South Island today, and a Severe Thunderstorm Watch has been issued for western parts of the North Island.
"Any thunderstorms that occur will likely be accompanied by localised heavy rain, hail, wind gusts of 110 km/h or more, and possibly a small tornado."
Earlier on Monday, a severe thunderstorm spawned a tornado and large hail which caused damage in New Plymouth.
Footage taken in the area shows the signature funnel shape of a tornado rapidly making its way across the sky.
New Plymouth local John Bamford was having breakfast this morning when the tornado hit.
"I saw it come straight through my windows," he told Newshub. "It annihilated my lounge. Took all the windows out, took tables and threw them up in the air. It annihilated trees that were 40 odd years old. Just a mess everywhere."
His wife was injured in the tornado, suffering a broken collarbone along with other minor injuries. She was treated by ambulance paramedics at the property.
