The final playoff berth will be decided at the Oceania Under 17 football Championship on Wednesday with New Caledonia and Papua New Guinea going head to head in Apia.
Defending champions New Zealand are already through to the semi finals and can guarantee top spot in Group A with a draw or better against the Cook Islands.
New Caledonia are second on nine points, two clear of PNG, who need a win to leapfrog the Francophones into the remaining playoff spot.
Papua New Guinea assistant coach Hans Gewebing is expecting a tough encounter.
"New Caledonians are good ball-players. They play more the same as Papua New Guineans but we know our strengths and we know their weaknesses, which we will try to capitalise on that and maybe eventually come out winners. We will give it out best out there - of course we have to win that game at all cost to make it in the finals so definitely we will have everything we can to win the game and make it through".
The other Group A match is a matter of pride between Fiji and Samoa.
