An independent review of the Hamilton V8 supercar race in April has shown that all resource consent conditions were met and the maximum number of people attending the event next year could increase.
The report covers issues of noise and a debrief with those involved and local people affected by the city circuit race track.
Ticket sales show that 172,522 people attended the three-day event.
The report says the event could cope with up to 240,000 people next year and has set a maximum of 80,000 people a day if organisers want to increase numbers.
A report into the economic impact of the event is due next month.
