While organisers for this weekend's event in Wellington cannot seem to give tickets away, next week's inaugural Sydney Sevens is set to put up the "house full" sign.
The future of Wellington Sevens is in jeopardy due to poor crowd numbers in recent years and a week out from the 2016 tournament just 12,000 tickets have been sold.
Organisers were hoping Sonny Bill Williams' presence in the New Zealand squad would boost sales but New Zealand Rugby chief executive Steve Tew says the cross‑code star's inclusion had not "made a huge difference to date".
Wellington is in the final year of its contract to host the New Zealand leg of the Sevens World Series and there are fears it could be moved to another city if it fails to fill Westpac Stadium this weekend.
