Tonga A led from start to finish to register their first win of this year's Pacific Rugby Cup against an ACT XV in Canberra on Sunday.
The visitors raced out to a 10-0 lead from a Kilifi Latu try and the boot of Viliami Hakalo.
Latu crossed again 10 minutes later while fullback Otulea Katoa also found the tryline to stretch the Tongan led to 22-13 at the break.
First five Sione Kite also scored with the score ending 29-20.
Meanwhile the Fiji Warriors take on the Force A team in Brisbane on Monday afternoon.
