Chiefs wing Sean Wainui scored five tries as his side delivered a dominant second-half performance to put the Waratahs to the sword in Sydney.
The Chiefs chalked up another win in Super Rugby Trans-Tasman after a second-half surge was enough to take them to a 40-7 victory over the Waratahs.
In the late dead rubber fixture at Brookvale Oval, the Waikato Chiefs closed out the regular season with a crushing 40-7 victory over hapless NSW Waratahs.
Sean Wainui starred in Sydney with a club record five tries as the Chiefs finished their campaign on a high.
The Waratahs, however, lost their 13th straight game having also endured a winless Super Rugby AU season.
Waratahs star Izaia Perese exited the game early with a suspected dislocated shoulder ahead of next month’s three-Test series between Australia and France.
The 24-year-old had been expected to be named in the Wallabies’ 38-man squad, which will be announced on Sunday.
