Police Ten 7 presenter retired Detective Inspector Graham Bell was at the site of the attack last week.
As part of the show he asked people to come forward with any information that could help identify the attackers.
Mr Bell said it was the second time this year Police Ten 7 had filmed a segment about a sexual attack at Kuirau Park.
At the beginning of the year, a 15-year-old was followed into a public toilet at the park by a man in his 40s, who then locked her in and sexually assaulted her.
Meanwhile, Mr Smith said police would still like to hear from anyone who has information about the latest assault, or was in the area of Kuirau Park between 2.30am and 3am on August 3.
