Auckland Westpac Rescue Helicopter staff battled some of the biggest waves they've had to deal with in 15 years during a dramatic rescue off the Northland Coast.
Mark Cannell, chief crewman for the rescue helicopter, described the conditions as "the second worst I have been out in, in 15 or 16 years".
However, they were prepared for them as MetService had already issued a strong wind and rain warning for the area on Monday.
The waves were so big they were breaking over the survivors in the liferaft which was languishing - and being thrown around - in the water.
It made for a tricky rescue but Cannell was impressed with his crew's ability to get all four out of the water in just over 20 minutes.
The two men are Pamela Pedersen's brother-in-law Steve, and Freedom Church member Bruce Goodwin. They have since been released from hospital.
The church posted on Facebook that Goodwin was "understandably in shock" but now recovering.
Cannell talked through their rescue today, and said they were already prepared for rough conditions in the area.
He described the conditions as "quite trying" as despite being a way offshore, the waves were so big they were breaking.
"The waves were quite a way offshore of course, but the swells were big enough with the wind conditions that some were starting to break.
"Instead of just a large swell, some of the waves were actually starting to crest and break over people. There's a bit of footage that shows the raft going under at one stage."
He said they could tell as soon as they got close - at a height of about 150m [500 feet] - that the swell was big.
"So once we were down at winching height [21m] they were pretty significant walls of water."
The first out of the water was Pedersen, followed by Mrs Pedersen.
However, getting the two men out wasn't easy as the liferaft was being thrown around by the massive swell.
"We just had to ensure that we got the medic in the right place."
It meant they had to anticipate the raft's movement, without the pilot - hovering about 25m off the ground - being able to see what's going on.
Meanwhile, one of the rescue chopper's sea swimmer was on the raft trying to hook them onto the winch.
"With that kind of sea state you can't keep tension on the winch cable, so of course as soon as the swell drops away, if you don't have enough slack then they get plucked out whether they're ready to go or not."
The rescue took about 22 minutes.
"I think 22 minutes, given what we were faced and the conditions, that was reasonably good."
Cannell said he wasn't able to talk to the two survivors after they were winched on board, but said they appeared relieved given what they had been through.
"Getting them into the aircraft, we got some heating on and then set about getting them back to appropriate clinical care as quickly as we could."
They were then airlifted to Northland Emergency Service Trust's Kensington Park Base in Whāngārei.

ACT Party leader David Seymour said its members were in a state of shock after the news of Pedersen's death.
He called Pedersen an "incredibly kind and hospitable man".
