But the wharenui and its carvings will stay in storage until Webb's Auction House confirms an auction date.
Webb's managing director Neil Campbell said it would be the largest sale of Maori carvings in New Zealand. He believed it should be sold to Te Arawa iwi.
"We always hoped the iwi would acquire it and bring it to life," Campbell said.
The wharenui was carved in the 1860s for the Ngati Tuwharetoa chief Hohepa Tamamutu. In 1886, it was sold to a European and used as a "novelty tea house".
