Allan Pearce notched Waitakere United's third with 12 minutes remaining, a goal that saw the forward become the league's all-time leading scorer with 63 goals from 121 appearances.
Pearce takes over the record he shared with former Auckland and Waitakere striker, Keryn Jordan.
In Dunedin, Tom Mosquera needed just eight minutes to score as a rejuvenated YoungHeart Manawatu beat Otago United 3-0 at Forsyth Barr Stadium.
Manawatu bagged a second after Suele Soromon evaded five defenders before laying on a delicious ball for Mosquera to half volley past Liam Little 20 minutes later.
He completed his hat-trick after a shot was parried by Little for Mosquera to finish with an easy tap-in.
Victory gives Manawatu just its second league win in 29 games and their first winning start to a campaign since 2009.
Meanwhile, a double by new signing Sean Lovemore ensured Hawke's Bay United got off to a winning start over Waikato FC.
The home side dominated possession for long spells of the game but missed opportunities cost the Declan Edge-coached side, who nonetheless look a polished outfit.
On Saturday, Auckland City put five past Canterbury United at Kiwitea Street, with Chris Bale, Albert Riera, Emiliano Tade and a brace by Adam Dickinson proving too much for the visitors.
Julyan Collett scored a scrappy goal for Canterbury from a corner, while All Whites midfielder Aaron Clapham's masterful panenka-style penalty kick was the only other consolation for last year's regular season runners-up.
The Phoenix Challenge returns after a two-year hiatus on Wednesday evening when Auckland City entertain Wellington Phoenix 'A' at Kiwitea Street, with kick-off set for 5.30pm.
Team Wellington and Canterbury United feature in an A-League curtain-raiser next Sunday before the Wellington Phoenix clash with the Central Coast Mariners.
Waitakere are at home once more, welcoming Waikato to Fred Taylor Park. Hawke's Bay hosts YoungHeart Manawatu in the heartland derby, with Auckland City playing for the third time in seven days and facing the long road trip to Otago United.
