Mr Box was described as "an amazing man of faith."
"We've got a tough two weeks ahead of us. But we face these things squarely, face them together and support one another anyway we can," Mr Newton said.
Owner of Box Construction, Mr Box had been a St Paul's parishioner for five years and produced films for the church.
The partners of those who had been on the trip were invited to the front of the church to lead prayers. Mr Newton later told the Herald there was a "sense of guilt around being a survivor."
Mr Newton also said this was not a church trip - "It was a group of friends, some of who go to this church."
Seven men - five heli-skiers, veteran guide Mark Sedon and the pilot Dave Matthews - were on board The Helicopter Line-operated Squirrel AS350 B2.
Matthews sustained minor injuries.
Director of Skyline Enterprises, which owns The Helicopter Line, Mark Quickfall said the five men were on a skiing holiday and staying in Queenstown. They were part of a larger group, some of whom went to Treble Cone yesterday instead.
"We're thinking of the poor fellow's wife tonight and his family. It's terribly devastating."
Quickfall understood the families of the skiers were supporting one another.
Senior Sergeant Gavin Briggs, of Dunedin, said all six survivors were injured - four seriously - and were flown off the mountain.
Briggs said four were later flown to Dunedin Hospital in serious but stable conditions.
Two were treated in Wanaka for minor injuries.
Transport Accident Investigation Commission (TAIC) spokesman Peter Northcote said investigators would travel to the crash site today.
Civil Aviation Authority (CAA) spokesman Mike Richards said the authority may be asked to help because of the scale and location of the site.
"I understand they clipped the mountain and the wreckage is spread 1000m down the side of the mountain. [The TAIC] may need more manpower ... it will be a very complex jigsaw puzzle for the investigators."
Otago Regional Rescue Helicopter chief pilot Graeme Gale said conditions were "calm and clear".
