They are from New Zealand, Australia, Vanuatu and the Rarotonga-based players.
Cook Islands Squash president Brett Baudinet said this year’s event was a special one as they have a fantastic international turn out.
“Generally we only have overseas players from New Zealand so it is great to see this year that we are getting more interest from other countries,” Baudinet said.
Rarotonga Squash Open is a singles tournament which has competition in both men’s and women's open division and division one grade.
“There are some top players here again this year which makes for an exciting draw,” Baudinet said.
Matches start from around 2pm daily and go until about 6pm, with the finals to be played tomorrow and Thursday.
“The courts are free for anyone to come and watch and we welcome everyone to come and watch some fun and exciting games.
“We have Paul from New Zealand, the defending men’s open champion from two years ago, back this year to try and regain the title. And our very own Anita Boaza in the women's draw defending her title from last year.”
