Conducted by Football Federation Samoa, the draw used seedings based on FIFA rankings.
In the men's event, six teams had been set to be placed in Group A and five in Group B but due to an mistake on the day, five teams were drawn for Group A and six for Group B.
To rectify this, a straight swap was carried out in the match schedules between the groups.
Group A features hosts Samoa, Tonga, New Zealand under-23s, Papua New Guinea and Vanuatu.
New Caledonia are the top seeds in Group B, alongside American Samoa, Tuvalu, Tahiti, Fiji and Solomon Islands.
