Strong thunderstorms are brewing in central North Island as the Tasman storm moves south.
It has lashed the top of the North Island today with rain sporadically bucketing down in Auckland, and parts of the region left without power.
Parts of Kaipara, Muriwai, Warkworth and Upper Waiwera had reported power outages on Christmas morning, which was expected to be restored during this afternoon.
MetService meteorologist Tui McInnes said there were quite a few lightning strikes developing across the North Island, particularly in the Manawatū but there were a few more "sparking up" around Taupō, Waitomo and the Waikato region.
"The front that brought the rain yesterday, that has moved south, but the edge that is winding into that low has now twisted across to Auckland," he said.
