Local resident Diana Moore told the Herald she had been up since 3am after being woken by the noise of helicopters.
"They've just been searching the whole time, they haven't stopped. They've been circling constantly."
After starting over Maungaturoto's main street, Moore said the helicopters were now flying low nearby over the country club on Bickerstaffe Rd.
"We don't get helicopters up here so it's quite unusual," Moore said.
She wasn't feeling too nervous thanks to the huge police presence in the area, but said she had been "a bit on guard" this morning.
"Hopefully [police] have got it all under control."
