Captain John Owen, the senior claims manager with The Swedish Club, the ship's insurer, said Resolve would be responsible for cutting the bow section to below the low tide line so the wreck would not be visible from the water.
Mr Owen said said helicopters would be used to lift sections as they were cut.
"This is a very difficult and potentially dangerous location to conduct operations and the Resolve plan means that we can continue to reduce the wreck in a controlled and safe manner," he said.
A spokesperson from Daina Shipping Co said cutting up the bow section of the wreck was estimated to take about six months. Meanwhile a senior team from Resolve arrived in Tauranga yesterday to begin preparations for the next stage of salvage.
The spokesperson did not know how many Resolve team members were in the Western Bay. He said the American company had taken over control of the salvage of Rena.
He said work would begin in the next couple of weeks. "Svitzer has already stood down from their duties but Braemar Howells have an ongoing contract and they will be working through the next stage of the project. [Braemar Howells] play a key role in monitoring the vessel and are part of the ongoing beach clean-up and environmental clean-up that is still required."
Debris from the Rena wreck has washed up on Bay of Plenty shores following bad weather and large seas this week.
There have been several reports of additional flotsam washing ashore in the area spanning Papamoa to Waihi Beach in the Western Bay of Plenty, and at Coromandel, Braemar Howells said.
A large sheet of container wreckage, measuring about 2m sq, washed up at Waihi Beach.
The scrap metal was taken to a recycling facility. Braemar's operations manager Neil Lloyd said 41 container-loads of steel scrap had been sent for recycling in the past week.
