More than 650 pilot whales had beached themselves along Farewell Spit at the tip of the South Island in two separate mass strandings over recent days.
It's not clear why the whales keep arriving on the spit next to Golden Bay.
'The whales will be moved off the shore and into the dunes, ' the DOC said in a statement.
What's most unnerving about the whole situation is that no one has been able to explain it, and it's not just happening in New Zealand - hundreds of whales have been running themselves aground all over the globe for years.
The shallow, sweeping spit is believed to interfere with the whales' navigation systems and is a regular scene of mass strandings. Officials declared nearly 350 whales dead.
Earlier Sunday, volunteers and conservationists were attending to 17 that were found stranded again.
The latest pod that got stranded late on Saturday are different from the group of 400 that was stranded on Thursday night at Farewell Spit in Golden Bay.
Germany elects 'anti-Trump' Steinmeier as new president
Schulz. "Isn't it a wonderful thing that Germany has become an anchor for hope for many people around the world?" said Steinmeier. Steinmeier is normally studiously diplomatic, but he strongly criticized Donald Trump during the USA election campaign.
The 17 whales were found stranded again Sunday morning but were refloated at high tide.
"We have staff in a boat offshore because there is a risk they could re-strand", she said.
Pilot whales are not listed as endangered, but little is known about their population in New Zealand waters.
Farewell Spit has been described as a whale trap. The problem with towing them out to sea or leaving them is that they could become gaseous and buoyant, and end up causing problems by floating into populated bays. It has been the site of previous mass whale beachings.
Doc's Takaka operations manager Andrew Lamason said the whales appeared to have left the area for deeper waters - good news for the rescuers that spent much of their weekend caring for the stranded marine mammals. "They've been singing songs to them, giving them specific names, treating them as kindred spirits".
There were references on social media in New Zealand suggesting the strandings and a 5.2-magnitude natural disaster early Sunday near Kaikoura, which was severely damaged by a 7.8 quake in November, may have been linked.
About 1000 whales beached themselves on the Chatham Islands in 1918 and 450 near Auckland in 1985.
