New Zealand Rugby chief executive Steve Tew has admitted ticket sales are still disappointing.
But in an interview with Newstalk ZB's Mike Hosking, Tew indicated that NZR has given no consideration to moving the tournament out of the capital.
The world had moved on from the days when the sevens stadium involved a boozy party atmosphere, Tew said.
"We are now responsible for the behaviour of people...the stadium licence holder has serious legal responsibilities under new legislation that came in a couple of years ago," he said.
