The Tamaki Titans have rejoined the Auckland Lions as the only unbeaten teams after four rounds of the 2007 Bartercard Cup competition.
The Lions were rocked early by the Wellington Orcas but worked their way back to a 16-10 halftime lead before exploding in the second half.
With a 28-point assault in the second 40 minutes they went on to win 44-20.
Among the Lions' try scorers was back rower Paora Packer from the Vodafone Warriors' Allied Work Force development squad. He started the season with his old team the Central Falcons but has now transferred to the Lions.
In Saturday's other matches, the Canterbury Bulls beat the Counties Manukau Jetz 40-22 in the early game at North Harbour Stadium while the Northern Storm prevailed 48-24 against the Falcons in Whangarei.
Following the Lions' win on Saturday, the Titans held off the Waitakere Rangers with a 26-16 win at Henham Park in Mt Wellington on Sunday.
Among the Titans' try scorers was Vodafone Warriors winger Cooper Vuna. He had been playing for the Vodafone Auckland Lions in the New South Wales Premier League but he returned to Bartercard Cup football this weekend.
In Sunday's other match, the Waicoa Bay Stallions had an 18-4 halftime lead against Harbour League in Huntly but failed to score another point as the visitors ran away to win 38-18.
