Southern remains unbeaten after three rounds of the Dunedin premier rugby competition and leads the points table with 14 points.

Southern 31
Pirates 0
Southern extended its decade-long hold on the Jack Hore Memorial Trophy with a convincing win over Pirates at Bathgate Park.
Pirates controlled the scrums but Southern dominated all other facets of play. Pirates was seldom out of its own half throughout the first spell, but a committed defence held Southern to only 13 points at the break.
In the second half, it was Southern's turn to remain captive in its own half, but it turned every opportunity into points.
Winger Nathan Cargo scored two tries for Southern and proved a handful when play went wide. Halfback Josh Walden provided superb service, and there was strong play up front from prop Mike Mata'afa and locks Tom Franklin and Ryan Thompson.
Patston gave a sound display, both at first five and then fullback, contributing 16 points through the boot.
Pirates committed too many handling errors and conceded a lot of penalties. Centre Ben Hanley and wingers Jury Arthur and Will Scorgie were the pick of the backs, while Craig Miller and Solomon T-Pole inspired a forward pack that was reasonably competitive.
Southern 31 (Nathan Cargo 2, Josh Walden tries; Ben Patston 2 con, 4 pen)
Pirates 0.
Halftime: Southern 13-0.
Taieri 28
University A 20
Midfield back Michael Collins enhanced his reputation when Taieri beat University A in a top-of-the-table clash at Peter Johnstone Park.
Taieri held a narrow 6-5 lead at the break but put its game together in the second spell to score three tries.
Collins was lethal when he was joined from the bench by Kieran Moffat and Ben Nowell in the second spell. They were a formidable backline combination.
Collins made a break up the midfield after 14 minutes and Moffat was on hand to score the try to put Taieri in front. Another Collins break led to Moffat's second try when the replacement used his strength to push off defenders inside the 22m.
Collins put the game out of reach when he intercepted a pass and scored when the students wereattempting to attack from deep inside their own 22m.
Taieri had too much strength and technique in the scrums and pushed the University A back. No 8 Charlie O'Connell and flanker Willis both had strong games.
Faasiu Fuatai was a good ball-handler and ran strongly at centre for the students. Nick Annear was a long-passing halfback and good on defence when his team was going backwards. The best of the forwards was openside flanker Jack Wolfreys.
Taieri 28 (Kieran Moffat 2, Michael Collins tries; Will McKee 2 con, 3 pen)
University A 20 (Sam McLachlan, Jonte Lexmond, Paul Grant tries; Guy Schwikkard con, pen). Halftime Taieri 6-5.
Alhambra-Union 25
Green Island 20
A disciplined pack and an enterprising backline helped Alhambra-Union gain its first win of the season at the North Ground.
Alhambra-Union played as a team and scored three well-constructed tries.
The kingpin of the backline was first five Peter Breen, with his quick and accurate passing and efficient tactical kicking.
The midfield of Colin Davies and Tili Puloka always looked dangerous and had a hand in all three tries. Davies used his silky skills to break through the defence and score the first, and set up the second when he made a break and sent a pass to unmarked winger Noah Cooper.
Puloka used his strength to score the third try after a prolonged build-up by the forwards.
Flanker Joe Wheeler, No 8 Graeme Cashmore and hooker Max Collet were the best of the forwards with their strong running and deadly tackling.
Green Island always looked dangerous with the ball but it was more by individual efforts than cohesive team attacks.
Loose forward Jackson Hemopo and prop Andre Clarke were the best of the Green Island forwards. Hemopo used his strength to break the defence and score his side's two tries.
Evergreen halfback Dean Moeahu was the best of the Green Island backs and Hayden McBride was safe at fullback.
Alhambra Union 25 (Noah Cooper Tili Puloka, Colin Davies tries; Peter Breen 2 con, 2 pen)
Green Island 20 (Jackson Hemopo 2 tries; Jared Fahey (2 con, 2 pen)
Halftime: Alhambra-Union 13-6.
Harbour 16
Kaikorai 12
Teenage centre Aleki Morris scored a brilliant solo try in injury time to clinch an upset win for Harbour at Watson Park.
It was Harbour's first win of the season and it was thoroughly deserved against a Kaikorai side which was lethargic in the pack and plagued by handling mistakes in the backs.
But it seemed Kaikorai would win when centre Jayden Spence, its outstanding player, latched on to a loose ball and sprinted away to score in the left corner to give it a 12-9 lead four minutes from the end.
Harbour powered straight back into Kaikorai territory and Morris finally conjured up the match-winning try when he ran on an angle, beat tackle after tackle and scored in the left corner, to the jubilation of his team-mates and supporters.
Kaikorai led 7-0 at halftime through a try by Spence, who scored under the posts after a straight, strong run. Harbour had threatened more and flanker Hadleigh May almost scored after a fine run by Joe Collins and winger Lisala Halaleva was denied a try when Lex Kaleca was sin binned for a late tackle.
Morris, Collins and replacement halfback Jamie Brown impressed in the Harbour backs while May and lock Charles Elton were non-stop forwards and prop Ben Nolan showed his experience in the scrum.
Spence was the pick of a lacklustre Kaikorai side, Tony Ensor gave tantalising glimpses of his ability but, like his team-mates, was prone to handling errors and Josh Renton was sound at halfback.
The Kaikorai forwards had their hands full trying to combat the hard-working Harbour pack but lock Blair Tweed gave his usual industrious effort.
Harbour 16 (Aleki Morris try; Joe Collins con, 3 pen)
Kaikorai 12 (Jayden Spence 2 tries; Matt Te Tana con)
Halftime: Kaikorai 7-0.
Dunedin 38
Zingari-Richmond 8
Zingari started and finished the game with a hiss and a roar. Unfortunately for the Colours, Dunedin dominated the middle 60 minutes.
In that period, Dunedin scored six tries, four of which were converted by Trent Renata, the Highlanders utility who orchestrated proceedings from first five and was the best player on the paddock.
The Dunedin backs were just a bit too slippery for their Zingari counterparts. Tumua Ioane was strong on the break, and Hugh Blake picked up a brace of tries with his speed to support play and his strength, which is a credit to the Highlanders conditioning programme.
The Zingari forwards were competitive and ably led by Brady Carmichael, the ubiquitous Chris Bell in his 149th game and Jesse Muir, who picked up a late consolation try from a forward drive.
Dunedin was all pace and possession, scoring four tries in the first half. The second half, however, was an was an exercise in sheep counting, littered by penalties, inaccurate passing, turnovers and a litany of errors.
The Zingari forwards battled manfully but their backs looked pedestrian and devoid of imagination.
Other players to stand out for Dunedin were diminutive hooker Aaron Clark, who was into everything and burrowed over to score a try. Beanpole Sam Poole was industrious when he took the field for Dunedin in the second spell.
Dunedin 38 (Hugh Blake 2, Kai Daniel, Trent Renata, Aaron Clark, Sam Poole tries; Trent Renata 4 con)
Zingari-Richmond 8 (Jesse Muir try; Shaun Driver pen)
Halftime: Dunedin 26-3.
