Overview
- Far North District and Whangārei District declared states of emergency for seven days, citing isolated communities, flooded roads including State Highway 1 at Mangamuka, and rising tides on both coasts.
- MetService's red heavy rain warning for eastern Northland forecasts up to about 320 mm through early Friday with peak downpours of 20–40 mm an hour and a stated threat to life from flooding, slips, and dangerous rivers.
- Fire and Emergency pre-positioned specialist water and urban search-and-rescue crews in Northland and Auckland, while marae opened as shelters and councils urged people who feel unsafe to leave early.
- Orange rain and strong wind warnings extend to Auckland, Great Barrier Island, the Coromandel Peninsula, Bay of Plenty, and Tasman, with gusts near 120 km/h expected and reports of road closures and power cuts overnight.
- Recent January storms left soils and slopes fragile in parts of Northland, raising landslide risk as this deep subtropical low delivers a multi-day mix of heavy rain, strong easterly winds, and large waves.
