For Pulu, the link with Umaga, the former Counties coach who gave him his first opportunity in the national provincial competition as a 19-year-old, is an important one. The former All Blacks captain has had a huge influence over the south Aucklander's career and for that he is understandably thankful.
After languishing as the number three halfback at the Chiefs behind Brad Weber and Tawera Kerr-Barlow, Pulu now has an ideal opportunity to take his rugby career back to where it was in 2014 when he played two tests for the All Blacks on the team's northern tour.
He is a muscular No9 - his defence has been noticeable in pre-season, just as it was against Scotland in Murrayfield in his last test when he came on as a replacement and put an enormous hit on an unsuspecting attacker.
And he is also a threat with the ball, a characteristic which Umaga will hope provides first-five Ihaia West with a little more space and time. Given the power and pace among the Blues' loose forwards and midfield, Pulu's ability to spark attacks by getting in behind the defence should put all teams on red alert.
West will probably be assured of the No10 jersey until April, but the return of second-five Sonny Bill Williams from injury could lead to Piers Francis, who will start in the midfield at AAMI Park alongside Rieko Ioane, putting increasing pressure on the first-five.
Pulu is also adaptable - he shone with the New Zealand sevens team last year despite not having a big background in the shortened format of the game - and said his time with the squad has helped his overall game.
"We all know that the sevens and the fitness base [it requires] is a different ball game," he said this week. "It has helped me. Coming back to 15s, I feel a bit sharper."
A sharp halfback is usually a dangerous one, and as Umaga seeks to start the new season in the best way possible against a team with its own consistency issues, it will be Pulu he looks to to set the standards.
