The Hawke's Bay Rugby Football Union is expecting another big crowd backing the Magpies to defend the Ranfurly Shield against Wellington on Sunday.
Union commercial manager Dan Somerville said ticket sales were going really well with about 6500 sold as of Tuesday morning.
He said that has them well on track for the Magpies' biggest crowd of the season for their biggest game of the campaign.
Not only does Hawke's Bay have the opportunity to secure the Ranfurly Shield until 2021 with a win, but they can also seal at least a top-two seed heading into the Mitre 10 Cup Championship finals.
The Magpies are currently three points behind first-placed Otago, and just one win against Wellington or Taranaki the following week would lock in a home semifinal, with Northland a further eight points back in third.
