Waimate upset Harlequins 21-18 and this win puts them in fourth place on the table.
Coach Warren Rooney was pleased his side stuck to their game-plan.
“The last 10 minutes were great, we had it all over them. The win gives us a lot of heart, it shows we can beat the top sides,” he said.
For Waimate, No 8 Blair Morris scored two tries while fullback George Williams kicked two first-half penalties and scored the winning try with moments to go.
The home-side trailed 13-11 at half-time, thanks to Harlequins winger Maile I’ongi’s 50m intercept try while prop Telusa Latu’s try extended the lead to 18-11.
However, Harlequins were reduced to 13 men for the last 10 minutes when prop Timaru Tafa received a red card for walking back onto the field while he was already in the sin-bin.
Harlequins coach Ken Wills said ill-discipline let his side down, but it was otherwise a good contest. Harlequins manager Gordon Rayner was puzzled why Tafa decided to walk back on to the field before his allotted time in the sin bin was over.
“I’ve got no idea what was going through his mind, it was just really strange,” he said.
Shortly after Tafa was red-carded for running back on to the field, his team-mate Sam Vea received a yellow card for a suspected professional foul, reducing the side to 13 men.
Waimate coach Warren Rooney said Harlequins players were getting “niggly”, but Rayner said Tafa was “nowhere near” that incident. “The referee red-carded him before he could even get to it. It was odd.”
