He passed inside to halfback Keegan Rowley, who drew the last defender and put Marinkovich in under the posts.
Whaka had worked themselves back into the game and were seeing more of the ball.
Right on halftime, after a period of sustained pressure inside the Tauranga 22m, hooker Jesse Mason Grant drove over the try line to score to the left of the posts.
First five-eighth Kelly Haimona converted to give Whaka a 17-15 lead at the break.
After halftime Whaka threatened to let the game get away from them as Tauranga scored two tries to lead 27-17 with 25 minutes to go.
A host of substitutions provided Whaka with some momentum and on the 65 minute mark they received a penalty right in front, which Haimona kicked to get his side back within seven points.
Whaka threw everything at Tauranga during the last 10 minutes but came up against some exceptional try line defence.
In the final seconds of the game the pressure paid off as, on the back of a scrum inside the Tauranga 22m, Whaka player Hiini Reweti bulldozed his way over the try line to score.
Haimona nailed the high-pressure conversion and the game finished 27-27.
Whakarewarewa coach Joe Savage said the way his players fought back for the draw would give them more self-belief going into the remaining games.
"A draw is better than a loss.
"The boys showed the resilience to come through and actually want to do better than previous weeks," Savage said.
While pleased with the draw, he was disappointed with the way Whaka let Tauranga take the lead early on.
"We try to come out with a hiss and a roar but unfortunately we got on the wrong side of the ref a few times and were camped at our own end.
"But even then we showed a lot of resilience trying to defend our line - the forwards played tremendously today."
He said, despite the yellow card, Marinkovich had an "outstanding" game.
"He brought inspiration to the team when we needed it and led pretty well.
"If we can put out a performance like that against Mount Maunganui next weekend I think we'll give ourselves a good chance of winning.
"Hopefully we can build on this performance."
