"It's a step up [today], I suppose. It's a good game."
There is almost little choice in the matter after the WRFU Council of Clubs, so concerned with the slaughter Ngamatapouri has visited on most of their opponents this year, passed a resolution recently to restrict any Senior club to a maximum of two recent Mitre 10 Heartland Championship players.
While Kubunavanua, whose surname Matthews still struggles with, will miss the final with an ankle injury, his brother 'Thomas' Kubunavanua - anglicisation of his name - is a part of the squad.
"Everyone else is ready to go."
When asked if Ngamatapouri wanted to "put on a show" in the championship game in front of a good crowd, Matthews felt there is little need to perform differently.
"Our backs are quite entertaining anyway, if the forwards step up."
However, their opposition today are no pushovers as Speirs Food Marton, themselves a Premier team up until the start of last season, have been the one side to challenge Ngamatapouri for the full 80 minutes.
If you don't use Ngamatapouri as a comparison, Marton have had an excellent year themselves by regular Senior standards - just two defeats and having ended Kelso Hunterville's streak of grand final appearances with victory in last weekend's semifinals.
This included pushing Ngamatapouri in the 40-32 loss at Marton Park on April 23, the only match that was remotely close.
President Isaac Greer, also a bench player for his team although he was in America during the semifinals, felt they will want to embrace the occasion.
"I'm quite looking forward to it, to be fair. We'll give it a go, anyway.
"You always go out to win and I imagine there will be no stopping us from doing that.
"You can't really ask for a much better year. A lot of these guys won't ever get the chance to play on [Cooks Gardens] again.
"It's a pretty awesome ground."
The club have arranged a bus from Marton Park and is expecting plenty of other supporters to make the car trip, while Ngamatapouri is hosting an after-party at 5pm at the Red Lion tavern.
Kickoff is at 12.45pm.
