The chief executive of Samoa's Pacific Games Office, Falefata Hele-Ei Matatia, said a new multi-sport gymnasium was being built from scratch to host the badminton and netball competitions.
"It's a multi-purpose gym so there'll be other sports in the future that will use it but for the Pacific Games it will focus on those two sports," Falefata said.
"The completion date will be around May next year."
The other ceremony was for the beginning of the refurbishment of Apia Park and the Samoa Aquatic Centre, Falefata said.
