The chief executive of Auckland's events agency has resigned suddenly, after an audit report criticised his previous role in Hamilton relating to the V8 Supercar event.
As mayor of Hamilton, Michael Redman was instrumental in bringing to the city an event that eventually lost $37 million - more than five times what had been predicted.
His resignation was announced after a day-long meeting of the board of Auckland Council's events agency, ATEED.
A brief statement gives no grounds for the resignation.
On Thursday an Audit New Zealand report criticised Mr Redman's performance - while first the mayor and then chief executive of the Hamilton City Council - in managing the city's involvement with the supercar event.
Mr Redman attended Thursday's Hamilton City Council meeting and later criticised the quality of the review carried out by Audit New Zealand.
Neither ATEED nor Mr Redman are making further comment.
Hamilton is cutting its ties with the event after next April.
