Former Cook Islands Prime Minister Dr Joe Williams, whose death was attributed to Covid-19 last week, is being hailed as a national hero.
The 85-year-old worked as a physician in Auckland and was continuing to help the Pacific community amid the coronavirus outbreak in the city.
At a state memorial service for Williams at the national auditorium in Rarotonga on Saturday morning, current Prime Minister Henry Puna paid tribute.
"Papa Joe had a remarkable career of many highlights, but it was the essence of a man who cared and wanted to serve people that puts him in the good company of our national heroes," he said.
"It was this essence of caring that was to ultimately cost him his life.
"How proud we all are to have had him among us as a Cook Islander, to have had him as a doctor, to lead us as a politician, and to serve our community as a mentor of knowledge and ideas."
