Auckland's first try was a lesson in how to punish opposition off turnover ball. Lock Scott Scrafton won the ball at the ruck, and there were assists by hooker Greg Pleasants-Tate and Bryce Heem before Akira Ioane received the ball some 40m out.
The No 8 has posted some impressive numbers this season, none more so than on the defensive end - where he started the clash with, can you believe, just one missed tackle, against his name. But he showed his pace and power on an irrepressible charge to the line, swatting away Marty Banks as if he were a troublesome fly.
Pleasants-Tate, who continued his strong recent form, also had a hand in the second, as did zippy halfback Kaito Shigeno, to wing Ben Lam. The killer blow, however, was administered by centre Charles Piutau, who retired hurt at the break. His grubber sat up for a rampaging Lam.
Auckland were beaten badly in the scrums, and even lost ball on their own put-in, but they defended stoutly to deny the Makos late in the first spell. Their tackling in general was sounder than Tasman's, who fell off 12 in the first half alone, while the home team missed just three in that period.
The pressure now goes on Canterbury to win in Christchurch to keep the Premiership final in the South Island. Should Taranaki triumph, as they did just a few weeks ago in the Garden City, then we return to Eden Park for the first decider since 2007. A Canterbury-Auckland final would be a reprise of the 2012 climax.
Auckland 44 (Akira Ioane, Ben Lam, Bryce Heem, Melani Nanai, George Moala tries; Simon Hickey 4 con, 2 pen, Jono Hickey con, pen) Tasman 24 (Kieron Fonotia, Trent Renata, Alex Ainley tries; Marty Banks 3 con, David Havili pen) Halftime: 20-3
