The future of Supercars racing in New Zealand is uncertain with a new deal for the Auckland SuperSprint yet to be secured.
The current arrangement between the Australian motorsport championship and Auckland Council's events arm ATEED expires at the conclusion of this weekend's event at Pukekohe Park Raceway.
Negotiations on a three-year deal to keep the event at the 2.91km circuit south of Auckland are ongoing but nothing has been finalised.
The 2018 Supercars calendar has the New Zealand stop scheduled for November and chief executive James Warburton is confident an agreement can be finalised soon.
