Authorities haven't tied down exact numbers of people missing, after the land gave way at Mount Maunganui's Beachside Holiday Park. 

The landslide took out tents, cars, caravans, a toilet block, and the hot pools about 9.30am this morning. 

The total unaccounted for is in single digits - including young people - with searchers including dog teams carefully probing the site.

The nearby Surf Club being used as an emergency hub has now been evacuated as a precaution.

Emergency Management Minister Mark Mitchell says geo-scientists are worried the Mount could slip again. 

He says police are still working out who was at the park today. 

"It's a matter of now going back, checking CCTV, camera footage and just working that out and just trying to get a very clear picture of who might have been impacted." 

Meanwhile, two people are still missing after a slip on Tauranga's Welcome Bay Road.
