Auckland Council is asking for proposals for a national stadium in the city.
The working group - formed in July - now wants expressions of interest to assess.
The winning venue will need to be capable of holding major events, have links to public transport and feature a retractable roof.
Chair and councillor Shane Henderson says the stadium should be able to compete internationally for big ticket events.
"Auckland's done this very well in the recent past, but we don't have a lot coming up in the future. This is one of the questions that has been around for many years around the city, so we want to just nail it."
