The new refurbished Marea Haus has been renamed as the Sir Manasupe Haus.
In announcing the renaming of the building this afternoon, Prime Minister Peter O'Neill said it was the Government's decision to honour Sir Manasupe Zurenuoc and name it after him.
Sir Manasupe will be retiring next month and has been serving the public service for more than 30 years.
The building was also officially handed over to the Government by Oil Search this afternoon.
