As the recovery mission on Whakaari gets underway, one of the pilots who rescued people after the eruption says weather conditions are good and he expects the operation to be wrapping up about midday.
One of the pilots who rescued people after the eruption, Mark Law of Kāhu NZ has been involved in planning the recovery mission.
He told Morning Report there was enough pressure "coming on from lots of different folks" that led to the recovery operation finally going ahead.
He couldn't say if helicopters would land on the island or give any more details around the operation.
But police this morning did confirm that the recovery team undertaking the operation had landed on the island.
"I think it's a good plan for the situation. I'm pretty confident by the looks of things and how it's all been put together. Everything seems to be ticking off so far. So, good news at this time."

Law said he assisted police with his local aviation knowledge and the location of the eight bodies because he had spent some time on the island right after Monday's eruption.
For the moment it is only Defence Force pilots on the mission, but Law said he was on standby if need be.
"They should be able to get the entire operation done without us."
Earlier Law suggested it could take 20 minutes to retrieve the bodies, but police say it could take several hours - that's because evidence needs to be collected for the coroner.
"It won't be a lot longer. They're well organised and well-rehearsed so it should be quite a short operation, all going well."
The weather was settled and with light winds on the volcano, it was a good window of opportunity, he said.
"It's nice to see the operation underway. We're all here to do our job and help where we can."
He estimates the recovery should be wrapping up about midday.
Karakia at sea
NZ Police national operations commander Deputy Commissioner John Tims said a blessing was held at sea with representatives of the families of the victims.
While the family representatives have returned to the mainland, the operation to recover the eight bodies on the island has commenced.
Paul Quinn, chair of Ngāti Awa Holdings, which owns White Island Tours told Morning Report before the recovery process started, a boat went out to sea for karakia about 4.30am.
Onboard it were about 30 people including Ngāti Awa, family members of the two of the White Island Tours staff, and family representatives of the Australian victims and the Australian High Commissioner, he said.
"Our role in that phase of recovery has been completed.
"The recovery operation on the island will be taking some time, because they need to do their forensic work."
He said the bodies would then be flown to the mortuary in Auckland.
Quinn said police were keeping them up to date.
"They're liaising much more closely with us as opposed to before."
