According to its website, Westpac Stadium seats 34,500 when full for a rugby match.
Westpac Stadium chief executive Shane Harmon urged fans buying tickets from scalpers to be wary. He said last year a number of people bought tickets from sites like Trade Me but were turned away at the gate, because the passes were cancelled.
"I think it's very unfortunate," Harmon said of scalping.
"We don't believe the numbers will be huge. We believe the vast majority of tickets will end up in the hands of people they want to."
The Hurricanes had kept prices affordable, he said.
"We do frown on anyone trying to take advantage of that."
Harmon said hosting another sold-out final was a privilege for the stadium.
