The 100-year-old chamber of Tonga's Legislative Assembly was destroyed by Tropical Cyclone Gita last month, forcing parliament to sit in the National Cultural Centre.
Tonga's speaker Lord Fatafehi Fakafanua said he was relieved and thankful for the overwhelming support from his regional counterparts.
Lord Fakafanua said it was crucial the Assembly continues to function at this difficult time for Tonga.
