The Auckland men, joint champions with Central last year, went three better than their female counterparts as they thrashed Northland 10-0 in their defence of the Challenge Shield. Up just 2-0 at halftime, the Aucklanders put their foot down in the second spell with Tom Wickham, Dwayne Rowsell and Alex Shaw playing strongly.
Midlands men looked like the other form team of the league as they claimed a comprehensive 3-1 win over a young North Harbour side in Hamilton. Kookaburra Tim Deavin made a quick turnaround after his bronze medal effort at the Olympics to lead the midfield for Midlands.
In other men's games, Capital won 4-2 at home against joint defending champions Central in a fast, open game. The goal of the match came late in the second half when Todd Gould buried the ball into the net after a lovely pass from Jake Smith.
Canterbury also started the NHL with a 3-1 win over neighbours Southern in Timaru with Trent Summers knocking in two goals.
NHL action continues tomorrow with round two matches at North Harbour, Auckland, Levin and Dunedin.
