Jimmy Gopperth's golden form continues unabated for London Wasps.

The 32-year-old former Hurricanes and Blues pivot chalked up 23 points, from eight goals and a try, as his club crushed Aviva Premiership leaders Saracens 64-23 on the weekend.

He was not the only Kiwi doing the damage. Former Wesley College, Steelers and Tonga centre Siale Piutau crossed for a double, as did former Auckland No 8 Nathan Hughes. Charlie Piutau appeared alongside his brother at fullback.

Sarries No 8 Samuela Vunisa, formerly of Taranaki, scored a try for his team.


James Wilson (11) and George Pisi (23) featured as Northampton won a decisive 35-7 victory over Halani Aulika's London Irish. The former Highlanders prop copped a yellow card.

Gloucester fielded Willi Heinz, John Afoa and Jeremy Thrush in their 28-6 win over Harlequins. Quins skipper Nick Evans kicked two goals, while Mat Luamanu, Ben Botica and Winston Stanley all played for Quins.

There was just one French Top 14 game played, a round 13 fixture in which Simon Hickey's four penalty goals saw Bordeaux-Begles to a 15-12 upset of Toulon. Luke Braid wore the No 7 jersey for the victors, while Ma'a Nonu's yellow card did not help Toulon's cause.

In the Guinness PRO12, Jayden Hayward kicked three important goals from fullback as Treviso defeated Cardiff Blues 13-7. The former Taranaki man was joined by Sam Christie (10), Filo Paulo (4), Dean Budd (8) and Chris Smylie (22). Rey Lee-Lo and Jarrad Hoeata appeared for the Blues.

There was a narrow 22-21 win for the Scarlets of Michael Collins, Regan King and Hadleigh Parkes over the Edinburgh of Phil Burleigh and Mike Coman.
