Mayor Len Brown yesterday received the title of Taua'aletoa in honour of his service to the Samoan communities of Auckland and the Pacific.
The title was conferred on Mr Brown by Prime Minister Tuilaepa Aiono Sailele Malielegaoi at his village of Lepa in a full traditional ceremony.
Mr Brown wore an "ula tupe", or money necklace made of $10 notes, headband and was dressed in ceremonial wear.
"I know the significance of the title, the commitment and expectation it carries," he told Talamua News Online. "I may be a 'palagi' by colour but my heart is with the Pacific people."
Mr Brown is the latest New Zealand politician to have been made an ali'i or high chief. Others include David Lange, Phil Goff, John Key and Winston Peters.
