This came after a delegation from the Solomon Island Visitors Bureau (SIVB) visited the area over the weekend.
The association was formed on Saturday after a meeting with SIVB.
SIVB was excused when the election took place.
And SIVB chief executive officer (CEO) Josefa Tuamoto after learning about the news said the trip has achieved one of its objectives.
He said the bureau wants to see changes and the formation of the new association is one of its achievements.
He congratulated the Marau Sound tourism association and said SIVB will work closely with them to make sure this part of Guadalcanal is being developed and promoted.
“I congratulate and thank operators for the formation of the new association to push the industry forward.”
The new association has a chairman, secretary, treasurer and other members.
