In the women's competition Brazil have been allotted Group C alongside Canada, Great Britain and Japan.

Group B comprises New Zealand, France, Spain and Kenya while Group A has Australia, the United States, Fiji and Colombia.

The top two teams from each group will qualify for the quarterfinals plus the two best third-placed teams.

The match schedule will be announced in mid-July.
