The double-header in Round 2 of the World Cup at Christchurch is anticipated to be the first sell-out of this year's event.
The newly opened ONE NZ Stadium in Christchurch, which started operating in March, will host the New Zealand Kiwis against the Cook Islands Aitu and the Kiwi Ferns facing France on October 25.
With only a few tickets remaining, it enhances the push for the NRL's 20th franchise, highlighting the strong demand for the sport among Christchurch locals.
The stadium is expected to welcome a team if Christchurch is selected for the NRL's expansion in 2029.
Having a World Cup sell-out would be a significant achievement for this New Zealand city, with the Kiwis' double-header being the only chance for fans to see their team at home.
The Orcas are vying for the new team spot alongside a fifth team proposal from Brisbane, which aims to fill the vacant western corridor.
Junior participation in rugby league is also rising in New Zealand, bolstering the Orcas' bid.
Over 140,000 tickets for the World Cup have already been sold, with significant interest in the opening match between Australia and New Zealand in Sydney.
Growing enthusiasm for the sport across the Tasman, coupled with the Warriors consistently filling their stadium, hints at New Zealand securing the 20th franchise.
The Kiwis have become even stronger with Kalyn Ponga's inclusion, a result of new eligibility rules from February.
