Webb's Auction House in Auckland says a traditionally carved rimu post may be permanently repatriated to New Zealand after spending more than a century abroad.
The centre post - also known as a poutokomanawa - is about 1.3 metres high and supports the ridge pole of an ancestral house.
It was designed by carver Anaha Te Rahui, who in 1864 was acknowledged as the leader of Ngati Tarawhai and led many Te Arawa campaigns on behalf of the government.
The managing director at Webb's Auction House in Auckland, Neil Campbell, says the carving has come from Italy and is now in New Zealand to be auctioned next month.
Mr Campbell says the owners would like it to fetch between $80-100,000, but he says the price will be dictated by the market.
