The emphasis at training this week has been on getting their systems right rather than focusing on Te Puna.
"We try not to look at whether a team is undefeated or not. Simply for me, realistically when it comes to round two everyone ups their game and any team on any day I reckon still can beat each other in the top eight.
"We know they are on a massive winning streak at the moment and they are doing well this year, so we are looking forward to the challenge. See what happens on Saturday."
Last week Tauranga Sports dispatched defending champions Mount Maunganui Sports 39-7 in probably their best 80 minutes of the season.
Mackintosh says it was one of those days when things just clicked for his team.
"We had been speaking about a lot of things we wanted to put in place, and things just hadn't been happening for us. That was a game we definitely played to our game plan and achieved a lot of the goals we had been working on in training, so that was extremely pleasing to see that actually happening on the park."
In other key games tomorrow, Te Puke host Whakarewarewa in what should be a tasty clash of two in-form teams. Greerton Marist and Rangataua Sports meet at Greerton Park in a game that will give the victor a significant top-four boost while Rotoiti are home on the shores of Lake Rotoiti against winless Mount Maunganui, who desperately need to win.
In Premier 2, Rangiuru are away to Marist St Michael's in Rotorua after being tipped up at Opotiki last weekend. Former All Black Liam Messam is turning out for Marist St Michael's, while Arataki are back home against Te Teko.
In Division 1, Judea are away to Paroa while Papamoa are home to Kahukura.
The Baywide women's competition is in action on Sunday. Rangiuru host Matata Women at Centennial Park, Rangataua are away to Waikite and Rotoiti and Whaka Women contest the Rotorua derby. Waimana have the bye.
