Six people, including two teenagers, are presumed dead after heavy rains triggered Thursday's landslide at Mount Maunganui on the island's east coast, bringing down soil and rubble at the site in the city of Tauranga, crowded with families on summer holidays.
Authorities have been working to identify the victims after human remains were found at the site on Saturday.
But a crack found at the site prompted recovery work to stop on Sunday, police Superintendent Tim Anderson said.
"As a result of that, we've had to pull all our staff out," Anderson told reporters at Mount Maunganui.
"We've had to do that for the safety of everyone concerned."
He did not specify when work would resume, saying the authorities were taking it "day by day at the moment".
Prime Minister Christopher Luxon said on Saturday it was "devastating to receive the news we have all been dreading", after the rescue operation shifted to recovery.
"To the families who have lost loved ones - every New Zealander is grieving with you," Luxon posted on X.
The heavy rain this week unleashed another landslide in the neighbouring suburb of Papamoa, killing two.
