Tahiti and Solomon Islands will face off for a place at the 2025 Beach Soccer World Cup on Saturday.
The winner of the Oceania Football Confederation (OFC) beach soccer Men's Nations Cup title also automatically qualifies for next year's world tournament in Seychelles.
Defending champions Tahiti hammered Papua New Guinea 16-5 in their final round robin game, while the Solomons lost a penalty shoot-out to Fiji, but still qualified.
Tahiti took 17 seconds to score in Thursday's match through Heirauarii Salem, but struggled for a period and PNG levelled the scores in the fifth minute through Ellygia Benard.
The underdogs then took the lead, courtesy of a well-placed volley from Benard but it lasted barely 30 seconds as Tahiti's Tamatoa Tetauira fired home to level.
Heirauarii Salem ended up with seven goals.
