He will be laid to rest in Tonga on a date yet to be confirmed next month.
Tonga's Prime Minister Siaosi Sovaleni Hu'akavameiliku told RNZ that Tu'i'onetoa would be missed.
"He was a Civil Servant for a very a long time so it's a hard to put into sentence what he's done for Tonga," said Hu'akavameiliku.
"He's ascent definitely going to be missed," he added.
