But Auckland are riding high and it was hard to shake the feeling that they were going to prevail.
Led by inspirational skipper Hadleigh Parkes they fought off an intense late Waikato charge to hold on to their 10-point lead and claim the Stan Thomas Memorial Trophy.
After a scrappy start, Auckland fullback Piutau made the first meaningful break of the match, using his explosive power and pace to surge over the line following a slick Auckland build-up in the 7th minute.
Penalties dominated the opening 15 minutes, with scrums and lineouts breaking up any fluidity and flow to the match.
The referee seemed the only one sure that Hohneck had managed to get the ball over the line for Waikato after 20 minutes, but the Mooloos didn't care, claiming it sheepishly.
Their joy was shortlived though, as a series of quick passes created space for Fekitoa out wide, who showed tremendous pace to easily skip past Waikato hooker Marcel Cummings-Toone.
Waikato skipper Alex Bradley drove the ball over the line from the back of a solid Waikato scrum five minutes before halftime to help reduce the deficit to six points at the break.
Joe Edwards struck first in the second half - just reward for a period of attacking dominance against a Waikato pack that was struggling to hold on.
George Moala increased the lead to 17 points before Bradley completed Waikato's scoring with his second of the match.
Auckland face Bay of Plenty, Taranaki and Wellington in their next three games, while Waikato face a demanding eight-day schedule which see them faces Bay of Plenty on Tuesday before travelling to Wellington on Saturday.
