Police say they are confident the body recovered from Nelson Lakes National Park yesterday afternoon is that of missing British tramper Andrew Ian Wyatt.
Search coordinator Constable Dave Cogger said Mr Wyatt had an "unsurvivable fall'' from Lake Constance Bluff.
Police were now trying to arrange a formal identification of the body.
Mr Wyatt's family in Britain had been advised, Mr Cogger said.
Police would like to acknowledge the efforts of search and rescue volunteers from Nelson, Golden Bay and Marlborough who worked alongside police during the operation.
