On Tuesday, 35-year-old Taupo woman Amy Jenny Brown tragically died in the water near the Haumoana river mouth after she tried to rescue two young children in trouble.
Her body was found early on Wednesday morning.
Meanwhile, a search and rescue operation is underway for a teenage boy believed to have been swept away in the Rangitikei River in Manawatu this evening.
Police were notified about 6pm that the boy was missing, a police spokeswoman said.
He was understood to have last been seen around 45 minutes earlier, near the bridge where State Highway 1 crosses the river south of Bulls.
"Police are out searching along with members of his family, and the rescue helicopter has also been assisting," she said.
She understood a jet boat was also searching on the river.
