The famed Pukekohe Circuit last hosted Supercars last weekend before its imminent closure early next year.
A sold-out crowd turned out for the event with local star Shane van Gisbergen bidding farewell to the track with a stunning win on Sunday night.
Stockouts were also reported at merchandise stores at the end of the weekend.
In a statement provided to the media after the event, Supercars CEO Shane Howard thanked Kiwi fans for coming out in force.
He also said the show continues to work on options for its future in New Zealand after Pukekohe.
Supercars are looking to reduce their schedule to 12 rounds next season, with NZ currently unsure of being on the schedule.
“What a fitting farewell event this weekend was here in Pukekohe,” Howard said.
“We would like to thank the thousands of fans who turned out in force over the three days, with a sold-out crowd on Sunday to cap off years of success at this incredible venue.
“That moment on Sunday afternoon when the crowd rose to celebrate Shane van Gisbergen’s emotional victory to win the Jason Richards Memorial Trophy will go down as one of the most memorable in the history of our sport.
“Following the success of this weekend’s event, we will continue to explore the potential for future hosting of Repco Supercars Championship events in New Zealand.”
Hampton Downs has long been seen as the logical replacement for Pukekohe given its proximity to Auckland.
However, this would still require negotiations with Aukland Unlimited, who are funding the event, given that it is technically across the border in Waikato.
There are also whispers of concerns about some track infrastructure.
Taupo International Motorsport Park is another option considered to be under consideration by Supercars.
However, a move this far from Auckland would likely require federal funding from New Zealand, as would any potential move to the South Island.
