The 20-year-old missed most of the season with one physical problem or another but started for the Blues in their famous victory over the British & Irish Lions at Eden Park in June, keeping the more experienced Ihaia West, who has departed for the Hurricanes, on the reserves bench.
It was West who came on and scored the late winning try following Sonny Bill Williams' offload, but Perofeta impressed enormously with his vision, composure and passing ability.
His wide cut-out pass was crucial in sending Rieko Ioane over for the Blues' first try of their win - easily the best under coach Umaga.
With heavy artillery in his backline, including midfielder Williams, and wing Rieko Ioane - plus wing Matt Duffie who has been called into the All Blacks for their northern tour, and a young man in Perofeta navigating the team around the field, it is clear that Pulu, 27, will play an important leadership role in 2018.
He helped the Blues cut the Crusaders to ribbons in Christchurch this year before the home side mounted an improbable comeback, and it is his running game which is his greatest strength, one that could create space for Perofeta and Williams.
Pulu, who played two tests for the All Blacks in 2014, is also seen as the right man to set the tone off the playing field - in the gym and on the training pitch. There is a feeling among some at the Blues that the All Blacks in the squad had too much of a say in setting the agenda when returning from playing the Lions, and that is unlikely to happen under Pulu's watch.
The Blues play an away game against the Highlanders on February 23 in their first match of the new season.
