UPDATE December 7:

The DomPost reports: Paraparaumu resident Mark Hunt said the Wharemauku Stream was the highest he had seen in nearly 18 years and showed no sign of dropping. He was concerned for his neighbours on lower ground on Kiwi Rd near the stream. “It’s the worst it’s been since the Paekākāriki floods. Usually it’s just a stream, but at the moment it’s like Niagara Falls.”
