"We've had them twice before and they're unbeaten so we're looking forward to seeing if they can retain that record," he said.
"There are Warriors connections with coaching and playing staff at Penrith, so there will be that extra edge. The good thing is that for both sides, this is the last major trial before the season starts, so they'll be turning out top sides, including State of Origin players.
"It's a rare opportunity for people in Rotorua to see football at this level."
Tickets are selling well, Mr McLeod said, and organisers hoped to see around 8000 people in the stadium for tomorrow's main game.
This time, they've introduced a family pass which includes up to three children, instead of two.
A helicopter is delivering the match ball and there will be a kids' activity area set up.
"The best thing is seeing people enjoying themselves," Mr McLeod said.
Gates open tomorrow at 10am.
