Department of Conservation (Doc) national funding for the rebuilding of the 40-year-old hut has been approved subject to a successful tender process.
Doc community relations programme manager Annette Smith, of Wanaka, was unable to disclose the likely cost of rebuilding until the tender process was complete.
A cleanup of the site took place last month and building work would probably begin in the next few months, she said.
Staff were working with an architect and a Doc engineer to complete the design.
Doc area manager Paul Hellebrekers said: "The rebuild project has given the department the opportunity to reconsider the hut facilities that are offered in the Siberia Valley.
"However, the hut will stand on the same footprint, orientated to make the most of the view up valley."
The hut will have sleeping capacity for 20 to cater for the roughly 2000 overnight visitors each year.
The New Zealand Fire Service investigation into the Siberia Hut fire has been completed.
The report concluded the cause of the accidental fire could not be determined although it was likely to have been centred on the lpg installation in the hut warden's quarters that formed part of the main structure.
The matter has been referred to Doc's health and safety manager to consider, Mr Hellebrekers said.
