A player to stand out was 110kg wing Robert Maxwell, who used his strength to score long-range tries in each half.
He resembled former All Black flanker Ian Kirkpatrick as he bumped off four defenders during a 60m dash for his second try.
Dunedin scored 10 tries and the team tally stands at 30 after just four games.
Dunedin is 13 tries in front of Southern and Taieri. Dunedin remains unbeaten, as are Taieri and Southern.
Southern and Taieri lead the competition with 19 points and are followed by Dunedin 17, Alhambra-Union 14, Kaikorai 11, Zingari-Richmond 7, Pirates 6, University A 5, Harbour and Green Island 1.
Centre Nick Jones scored three tries when Southern beat University A 37-26.
Second five-eighth Michael Collins displayed a touch of class when Taieri beat Green Island 26-15.
Alhambra-Union suffered its first loss of the season when Kaikorai fullback Tony Ensor intercepted a pass on his own 22m and ran 80m to score the winning try. Kaikorai won 16-10.
Pirates gained its first win of the season when it beat Harbour 29-20.
Dunedin 62
Zingari-Richmond 3
Dunedin turned up the heat by scoring four tries late in the first spell to take the heart out of the Zingari-Richmond defence at Montecillo.
The powerful Dunedin forwards had speed and ran and passed like backs. The Zingari defence had no answer as four tries were scored in the last five minutes to give Dunedin a 36-3 lead at the break.
The most telling moment came when big prop Kelsey Miller ran out of his own half for 40m, put in a centering kick that was snapped up for one of Dunedin's tries.
It was game, set and match when Dunedin added two quick tries in the second spell to lead 50-3.
One of the most formidable players in the Dunedin backline was big wing Robert Maxwell, who resembled former All Black flanker Ian Kirkpatrick when he scored his two tries.
He exploded up the paddock on a 40m run in the first spell and during his 60m run for his second-half try he bumped off four tentative tacklers.
The other important ingredient in Dunedin's win was the work of the loose trio of Mark Atkins, Tom Verdonk and Mitchell Zandstra.
Zingari had its chances when its forwards dominated play in the first 20 minutes.
The backline had three scoring chances with the line open but the backs bungled each attempt.
Dunedin 62 (Robert Maxwell 2, Kai Daniel, Ashton Tuck 2, Jesse Toto, Mitchell Zandstra, Richard Thompson, Tumua Ioane, Sam Poole tries; Liam Edwards 6 con), Zingari-Richmond 3 (Mark Hunter pen). Halftime: 36-3. Referee: Rob Wells.
Southern 37
University 26
Nick Jones was in dynamic form and his hat trick of first-half tries turned the game at the University Oval in Southern's favour.
It was a free-flowing game and both teams gave the ball air and were prepared to counter-attack.
Accurate goal kicking by University first five-eighth Stephen Fenemore kept the students in touch and they led 13-10 after lock Sam Henry scored.
Jones, the Southern centre, had scored an early try but he stepped up to another level in the final minutes of the spell to score two tries to give Southern a 24-13 lead at the break.
The Southern midfield combination of Jones and Apelu Alapati cut huge holes in the student defence. Alapati stretched the gap to 15 points when he scored early in the second half.
The students were forced to play catch-up rugby after that and it was always going to be difficult.
Southern first five-eighth, Ben Patston, controlled play effectively and kicked five goals to score 12 of his team's points.
Added pressure was applied in the forwards by flanker TJ Ioane and lock Tom Franklin.
No 8 Paul Grant and Henry were the best of the student forwards.
Southern 37 (Nick Jones 3, Apelu Alapati, Dan Kittow tries; Ben Patston 3 con, 2 pen), University A 26 (Luke Balvert, Sam Henry tries; Stephen Fenemore 2 con, 4 pen).
Halftime: 24-13. Referee: Mike Smaill.
Taieri 26
Green Island 15
Taieri beat Green Island at Miller Park because of the superior structure of its game and by the ability of its backline to attack from all parts of the paddock.
Green Island had some talented individuals who put pressure on the Taieri machine and upset its rhythm.
The most notable of these was big prop Junior Sala, who was having his first game since breaking his eye socket in a pre-season warm-up game.
He ran like a rampaging bull with the ball in hand and scored the first try. On defence he pounced like a panther on the Taieri attackers.
He was backed up by flankers Tala Moli and Mika Mafi who ran like backs and wrestled the ball back at the breakdown.
It was Moli who made the break for Green Island's second try that was scored by lock Jackson Hemopo to keep Green Island in touch. Taieri led by just one point, 13-12, at the break.
It was a free-flowing game that suited the upfield thrusts by the Green Island individuals.
But they could not match the co-ordinated play of the Taieri backline as they counter-attacked from deep within their own 22m.
The Taieri backline always looked dangerous but they failed to exploit their monopoly of ball because of a lack of precision, and lacked patience.
The most exciting back was first five-eighth Ben Nowell, who ran with pace at the defence, while midfield back Michael Collins and wing Shannon Young impressed.
Collins showed a touch of class when he stepped past the defence 40m out and set up the first Taieri try, scored by hooker Will Hurst.
Hurst and the loose trio of Charlie O'Connell, Nathan Young and the snarly Karl Bloxham were the best of the forwards.
O'Connell and locks Matt Davidson and Kurt Webster gave Taieri a two-to-one advantage in the lineout.
Taieri 26 (Michael Collins, Shannon Young, Will Hurst tries; Ben Nowell con, 3 pen), Green Island 15 (Junior Sala, Jackson Hemopo tries; Joe Bartlett con, pen). Halftime: 13-12. Referee: Gareth Reed.
Kaikorai 16
Alhambra-Union 10
Fullback Tony Ensor scored a spectacular runaway try nine minutes from the end to clinch a deserved win for Kaikorai over previously unbeaten Alhambra-Union at Bishopscourt.
Ensor swooped on a loose pass inside his 22 and sprinted 80m to the posts to give Kaikorai the lead for the first time.
Kaikorai dominated territory but trailed 3-7 at halftime. It turned down four kickable penalties and was not able to penetrate a well-organised Alhambra-Union defence.
Wingers Sam Young and Bryce Morgan both went close to scoring but it was a half of lost opportunities for Kaikorai.
Peter Breen scored Alhambra-Union's try early in the game when he sidestepped and broke some ineffectual tackles to score by the posts.
Alhambra-Union retained the lead 10-6 until Ensor's breakout try and Cameron Rutherford rammed home the advantage with a penalty from 40m.
Rutherford kicked four from six for Kaikorai while Ensor, apart from his try, was the most dangerous attacking back in the game.
Lee Allen and Adam Hill were tigerish loose forwards, while hard-working lock Blair Tweed had a solid all-round game in what was a committed Kaikorai pack.
Alhambra-Union spent much of the game on the back foot.
Mike Moeahu and Breen controlled play well in the inside backs and lock James Willocks and hooker Ben Peraira were good value in the forwards but, overall, the score reflected Kaikorai's greater desire to win.
Kaikorai 16 (Tony Ensor try, Cam Rutherford con, 3 pens); Alhambra-Union 10 (Peter Breen try, con, pen). Halftime: 3-7. Referee: Adam Morrison.
Pirates 29
Harbour 20
The tight five helped kick-start the season for Pirates with a bonus-point 29-20 victory over Harbour at Hancock Park.
Harbour started well, using the elements of the sun at its back and a tail wind.
A sensational try to Craig Sneddon in the opening minutes promised much from last year's championship finalist.
Pirates were quick to reply through some Kieran Fowler magic down the right flank before both sides then exchanged further five-pointers minutes apart as the game appeared as if it was going to open up.
But it was the engine room of the Pirates pack that began to exert itself and dominate both at the breakdown and set piece.
This pressure began to show late in the first half when an overthrown ball at the lineout cost Harbour dearly as it was gathered in at the back by prop Craig Miller, who, with a turn of speed, burst up field 30m before off-loading to Marshall Suckling to hand Pirates a 17-13 lead at the break.
The Pirates pack dominated the first 20min of the second half, an early tighthead cementing its intentions up front.
Openside flanker Shaun McCarroll capped off a top game to stretch his side's advantage and secure the bonus point try.
That was followed quickly afterwards with a second try to halfback Steve Bruce, who was excelling behind a dominant pack.
Harbour always appeared as though it may break out. Halfback Johnny Legg, with a try that brought Harbour back into the game in the second half, was lively in broken play and gave good service to his outside backs and supported the good work from the loose forward trio of Sam Ready, Angus Duckett and Eben Joubert.
Pirates 29 (Steve Bruce 2, Kieran Fowler, Marshall Suckling, Shaun McCarroll tries; Kieran Fowler 2 con), Harbour 20 (Craig Sneddon, George Folau, Johnny Legg tries; Ollie Cuthill 1 con, 1 pen). Halftime: 17-13. Referee: Jeff Grubb.
