Moana Pasifika officially end Waratahs' finals hopes

But Saturday's four-tries-to-two defeat at Go Media Stadium left the last-placed Tahs with no mathematical hope of scraping into the finals.

Instead they must beat the Queensland Reds in their last game of the season next Friday at Allianz Stadium to avoid sending off outgoing coach Darren Coleman with the dreaded wooden spoon.

Wiped out of every one of their contracted front-rowers, the Waratahs always faced an uphill battle competing physically with the bruising Moana Pasifika forward pack.

And so it proved as the Pacific Islanders ran in the first four tries to open up a match-winning 27-0 lead inside the hour mark.

Powerhouse No.8 Lotu Inisi collected a double after fullback Kyren Taumoefolau crossed for the opening try in the 15th minute.

Inspirational former Waratahs and Wallabies prop Sekope Kepu brought the house down when he stormed over to put the icing on the cake.

The Waratahs had to settle for two late consolation tries to back-rower Langi Gleeson and strike centre Izaia Perese.

While the Tahs can start planning for 2025, Moana's fourth win of the season has given them a slim hope of making the finals if they can topple struggling defending champions the Crusaders next week in Christchurch.
