Gardiner, who is a football development officer at WaiBop, was hoping for a better result in last week's 1-3 loss to Ellerslie.
"To be honest, we are disappointed about losing the first game of the season. We had a fairly productive pre-season in how we wanted to play the game and implementing our style of play," he said.
"But we hadn't faced the opposition of the level we are playing at, and we got caught a wee bit on the hop in the first half. The pace of the game was probably greater or a higher tempo than we faced in pre-season.
"We certainly improved in the second half and showed signs of the stuff we had been working on and were probably a little unlucky to maybe not get a point out of the game."
Gardiner has several key players still out injured but is confident of taking the three points from Sunday's match with Oratia.
"We are looking to rectify last week's result and put things right and get our first win of the season to get ourselves off the mark."
Kick-off on Sunday is at 3pm with Tauranga v Oratia Reserves at 12.30pm.
