The fleet-footed Tuitavake scored a hat trick for North Harbour B in its impressive 53-19 win over Otago B.
Tuitavake started at second five-eighth and scored a try in the first half, receiving the ball about 30m out and seeing off three defenders with a clever run and burst of acceleration. He added two in the second after being pushed to the left wing.
The Blues flier, who debuted for the All Blacks this year, said after the game he enjoyed the match and the chance to have a hit-out with some club-mates.
"You know you have come down to the next tier, but the skills from the guys are still there. The game was probably not as structured as the higher level, but the guys flew into it and were full of enthusiasm," he said.
Tuitavake broke a cheekbone in the test against Samoa in early September and got back on to the playing field only last week.
But with North Harbour unable to make the quarterfinals, Tuitavake, who needed game time, was asked by the All Black selectors to play for North Harbour B.
It will be the only match he plays for the side. He is ineligible for the semifinal next week because he has not played enough B games.
There had been speculation Tuitavake would be heading overseas, but he said on Saturday he had signed on for another year with Harbour and the New Zealand Rugby Union, which will be a boost for a struggling Blues franchise.
He played one year for the Highlanders, in 2005, and said he had learned much in that year, and enjoyed the friendliness of the southern franchise.
His real goal at the moment was the end-of-year All Black Grand Slam tour, and with no other games on his calendar until the team was announced in two weeks, he said he would be training hard.
"I'll be really training hard out. I've got to get fit."
The All Blacks were to hold a training camp for players not involved in the Air New Zealand Cup final next week.
Tuitavake was joined in the North Harbour backline by All Black team-mate Rudi Wulf, who did not score a try but always looked dangerous.
North Harbour was steered around the paddock well by Ben Botica, son of former All Black Frano Botica, the North Harbour assistant coach.
Otago B competed well in the scrum and won a few line-outs, but made errors at crucial times against a talented and large North Harbour side.
Best for the home side were prop Sam Hibbard, flanker Hoani Matenga and winger Karne Hesketh.
The loss means Otago B did not make the semifinals.
• North Harbour B 53 (Anthony Tuitavake 3, Tua Saseve, Ryan Wilson, Robbie Colhoun, Luke Hamilton tries; Ben Botica 2 penalty goals, 6 conversions), Otago 19 (Karne Hesketh, Paul Grant, Richard Cowley tries; Glenn Dickson 2 conversions). Half-time: North Harbour 22-7.
