The Kiwi Ferns sent Fetu Samoa out of the 2026 Rugby League World Cup with a 32-0 semifinal win at McDonald Jones Stadium.
Four Bulldogs players featured for Samoa, including new signing Mercedez Taulelei-Siala.
NRLW Rookie of the Year Taulelei-Siala made 65 metres from eight runs, while Monica Tagoai gained 61 metres, broke two tackles and made 11 tackles.
Mary-Jane Taito played 59 minutes in the middle, making 27 tackles and missing one for 93.1 per cent efficiency.
Leilani Wilson played all 70 minutes, recording 65 metres, a tackle break, an offload and 27 tackles.
The quartet's tournament experience could benefit them ahead of the 2027 NRLW season.
In the men's semifinal at Allianz Stadium, Australia beat Samoa 44-12, with Bulldogs teammates Jacob Preston and Stephen Crichton facing off.
Preston scored in the 13th minute, his third try in as many games for Australia, and helped create Bradman Best's try with a pass after collecting Cameron Murray's offload.
He made 34 tackles, missing one, and finished with 95 metres, a line break, a line-break assist and a try assist.
Crichton scored a try and kicked two goals for eight points, adding 17 tackles; his tournament tally was 40 points from three tries and 14 goals.
Australia's discipline proved costly for Samoa, whose captain had an early try narrowly ruled out.
Preston and Australia will meet New Zealand in Sunday night's final at Suncorp Stadium.
