St George Illawarra kept their NRLW premiership hopes alive with a 26-6 victory over the New Zealand Warriors on Sunday.
The Dragons, Roosters and Warriors all have a chance of qualifying for the grand final against Brisbane heading into the final round.
The Dragons will face the Sydney Roosters in a stand alone clash at Leichhardt Oval on Sunday after the Warriors take on the Broncos on Saturday at the Sydney Cricket Ground.
St George Illawarra trailed 6-0 at half-time in Auckland before storming home with 26 unanswered points.
Shaylee Bent, Tiana Penitani, Maitua Feterika, Jessica Sergis and Botille Vette-Welsh scored five tries between them in 17 second half minutes for the Dragons, with shire Jillaroo Maddie Studdon adding three conversions.
Onjeurlina Leiataua had barged over from close range for the Warriors in the first half.
The Dragons are second on two points but with a +10 for and against advantage over the Warriors (-16). The Roosters have lost both their opening games but a strong win over the Dragons and a Warriors loss to the Broncos could see them qualify of the grand final.
Brisbane downed the Roosters 20-0 in the other round two game.
