New Zealand heavyweight boxer Joseph Parker could make the first defence of his WBO world title in Auckland.
Parker's promoters Duco Events have won the rights to host the title defence against Britain's Hughie Fury.
WBO Boxing's President Paco Valcarel tweeted details of the bid and bout claiming the fight would take place in Auckland on April 1st.
But Duco director Andrew Higgins said the venue had yet to be confirmed.
"It's such a huge amount of money that we have to see where it stacks up," he told reporters at the Auckland Nines.
"We've had an inquiry out of Singapore about taking it to a casino. In Manchester, Hughie Fury's home town, fans by tickets big," he said.
"But we would like to hold it here (Auckland) so our job now is to talk to our supporters and sponsors and see if we can make it work."
Hughie Fury, 22, is the WBO's mandatory challenger. He is the younger brother of former world heavyweight champion Tyson Fury.
Duco's winning purse bid was for a little more than $4 million. The bid was conducted by the World Boxing Organisation overnight.
The split of the purse will be 60-40 in favour of Parker.
Parker has a 22-0 record as a professional and won the WBO title with a points victory against Mexican-American Andy Ruiz in Auckland in December.
