University A 48
Pirates 10
First-five eighth Chris Noakes was in sublime form for Varsity A, scoring 26 points from two tries, five conversions and two penalties.
His second try was the pick of them, as he gathered in the ball following a breakdown mid-way through the second spell, and ran 25m to score against a Pirates side beginning to buckle under the constant pressure.
Frustration by Pirates led to two of its players being sin-binned.
Prop Daniel Johnson spent the final 10min of the first spell in the bin, while captain Ross Kennedy, took an early shower 6min from full-time, when he paid the price for his side's constant infringing.
Halfback Sean Romans and Noakes were outstanding and the midfielder Dan Snee provided extra penetration and gave heart to a hard-working forward pack.
For Pirates, Kennedy, Warren Kearny and Craig Stanway, were always in the thick of the forward exchanges.
University A 48 (Chris Noakes (2), Randall Kamea (2), David Thompson, Jeremy Aldworth tries; Chris Noakes 2 penalties, 5 conversions; Shaan Davis 1 conversion), Pirates 10 (Warren Kearney, Craig Stanway tries).
Half-time: 27-5.
Referee: Todd Pullar
Harbour 51
University B 0
A 51-0 victory, featuring nine tries, elevated Harbour through to the top six to contest the championship round of the Metropolitan Premier division 1 championship.
Playing with a strong wind at its back in the first half, Harbour had bagged the bonus point it required to secure a place in the top six.
University B played with pride, but suffered with a high penalty count awarded against it by rookie premier referee Adam Morrison.
University B did well to hold the Harbour side to 22 points at the break and keep it scoreless for the first 14min of the second spell.
Harbour found a second wind through inspirational open-side flanker Jason Kelly, who ignited Harbour with some good go-forward ball after captain Peter Mirrieless went off with an injury.
The pressure exerted by the Harbour pack took its toll on the inexperienced University B side which folded to let in another five tries over the final 25min.
Kelly was well supported by fellow loose forwards Nathan McLachlan and Brad Griffiths, while locks Mal Aitken and Aaron Larsen featured in the tight.
Tom Hiratsuka ignited a backline in which outside backs Kelly Kolberg, Aaron Bancroft and Corey Kara excelled.
Chris Burke led the University B pack by example with some outstanding play in the loose, while Tim Mullins provided some excellent service from halfback and Henry Holdway put in some useful clearances from first-five eighth.
Harbour 51 (Jason White (2), Aaron Bancroft (2), Kelly Kolberg, Nathan McLachlan, Mike McDonald, Malcolm Aitken, Conrad Joblin-Hall; Conrad Joblin-Hall 3 conversions, University B 0.
Half-time: 22-0.
Referee: Adam Morrison
Kaikorai 10
Zingari Richmond 0
In a game of lost opportunities, Kaikorai defeated Zingari Richmond 10-0 in the Tom Watkins Memorial at Bishopscourt.
Zingari Richmond took the game to the Kaikorai forward pack in the first half, but was unable to turn its efforts into points, and trailed 0-3 at the break.
Hamish Cooper provided an excellent platform for the Zingari Richmond pack with six clean line-out takes from his side's own throws.
It also stole three off the Kaikorai throw.
His brother, James, along with Chris Bell, proved great service to Zingari Richmond with pick and goes.
A puzzling feature of Zingari Richmond's play was its decision to run the ball rather than convert two kickable penalties in the first half.
Kaikorai enjoyed a feast of ball and opportunities throughout the second half only to be let down by handling errors.
However, Mark McGregor was solid in midfield, while Jim Stevenson and Alando Soaki were the pick of the Kaikorai forwards.
It is likely to be a game Zingari Richmond may regret for not making the most of its opportunities.
The only try of the match resulted from the sin-binning of its captain, Mason Pomare, for throwing a punch with Kaikorai hot on attack.
From the resulting line-out Kaikorai took the ball in and drove No 8 Ben Inglis across to score.
Kaikorai 10 (Ben Inglis try; Andrew 1 conversion, 1 penalty), Zingari Richmond 0.
Half-time: 3-0.
Referee: Doug Rodgers.
Southern 28
Dunedin 28
There was enough to show that Dunedin will be a threat in the final rounds when it retained the Ron Reggett Memorial with a 28-28 draw with Southern at Bathgate Park.
The Dunedin forwards, led by captain Scott McKee from No 8, got the better of the Southern pack and were unlucky to be down 0-14 after 17min.
However, a leg injury to Southern halfback Lewis Hancock turned the tide back in Dunedin's favour, and two penalties to Tumua Ioane reduced the deficit to 6-14 at the break.
Both sides took a fresh approach to the game in the second spell and it was Dunedin which drew first blood with a try to second five-eighth Scott Milne, the conversion closing the gap to one point at 13-14.
Dunedin took full toll of the sin-binning of Southern's Andrew Clark to score through Richard Naylor and take the lead.
But then it was Dunedin's turn to have a player sin-binned when Bronson Ross was yellow carded with 10min remaining. This enabled Southern to regain the lead through Jarid Bradley, only for Dunedin wing Joe Bradley to retake the lead and Ioane to add a penalty soon after. With time up, Dunedin appeared likely at 28-21, but Southern dug deep for a final assault in a movement that swept the length of the field.
Warren Moffat, in his 100th premier game for Southern, scored under the bar for Tom Newton to convert and secure the draw.
For Southern, Apelu Alepati was prominent in mid-field, while in the forwards, flanker Carl Anderson, along with Moffat at prop, had a high workload.
For Dunedin, McKee, Richard Naylor and John Crossan shone in the loose, along with Chris Damsteegt in the tight.
Southern 28 (Apelu Alapati, Lewis Hancock, Jarid Bradley, Warren Moffat tries; Tom Newton 1 conversion; Hamish McKenzie 1 conversion; Lewis Hancock 2 conversions).
Dunedin 28 (Scott Milne, Richard Naylor, Joe Bradley tries; Tumua Ioane 3 penalties, 2 conversions).
Half-time: Southern 14-6.
Referee: Mike Woodhouse.
Alhambra-Union 29
Green Island 5
A positive brand of rugby in the first half secured a 29-5 victory for Alhambra-Union over Green Island at the North Ground.
A penalty try was awarded in the opening minutes to Alhambra-Union when hooker Ben Pereira ran 40m only to be cut down with a dangerous head-high tackle by Green Island wing Alipate Fatafehi, who was given 10min on the sideline.
Alhambra-Union made the most of his absence, scoring through a piece of Karne Hesketh magic, finished off by fullback Casey Stone.
Fatafehi's return halted any addition to the 14-0 scoreline, until he redeemed himself with a try to reduce Green Island's deficit.
A penalty to Luke Reihana stretched Alhambra-Union's advantage soon after, and the game drifted into a holding pattern.
But two tries in as many minutes to Perreira as half-time approached gave Alhambra-Union an appearance it was about to dominate the second half.
But it was not to be.
The outside backs always looked to threaten for Alhambra-Union.
Hesketh especially appears to be at his game-breaking best.
Casey Stone was always looking for work and options to attack, as too Doug Edwards and Luke Reihana.
In the forwards, the tight five had a solid hit-out, with Michael Patillo especially dominant at line-out, and Matt Clutterbuch inspirational as a leader about the field.
Mark McIlroy was the pick of the Green Island backs, supported well by both Marc Ellison and Ben Smith.
In the forwards Jason Bint and Brett Campbell put in a lot of good work.
Alhambra-Union 29 (Casey Stone, Ben Pereira 2 tries; penalty try; Luke Reihana 3 conversions, 1 penalty), Green Island 5 (Alipate Fatafehi try).
Half-time: Alhambra-Union 29-5.
Referee: Dave Kennedy.
