After Mitchell Hunt opened the scoring from the tee, Levi Aumua scored the first try of the Mako season, capitalising on sustained pressure to slip through some poor defence close to the line
Canterbury hit back with a penalty from the boot of Brett Cameron, closing the gap to seven points at the break.
It took just one minute after the interval for Tasman to strike again, with loose forward Quinten Strange crossing the stripe following a bounce pass from hooker Andrew Makalio. Six minutes later, the Mako were over the line again, this time through winger Solomon Alaimalo – fresh off a breakout Super Rugby campaign with the Chiefs.
However, when Tasman's Blair Prinsep was shown a yellow card in the 69th minute, Canterbury capitalised. After struggling all game to string an attack together, substitute hooker Greg Pleasants-Tate crashed over from close range, and the big fella found himself with a double seven minutes later when he was the benefactor of a strong lineout drive.
The two late tries made the scoreline much more respectable for the red and black, flattering them in what was a dominant outing from the Mako.
Tasman 25 (Levi Aumua, Quinten Strange, Solomon Alaimalo tries; Mitchell Hunt 2 cons, 2 pens)
Canterbury 17 (Greg Pleasants-Tate 2 tries; Brett Cameron 2 con, pen)
HT: 10-3
