Maori academic and writer Dr Ranginui Walker has died aged 83.
The academic passed away at his Auckland home. He would have been 84 tomorrow.
Dr Walker dedicated much of his life to promoting Te Reo Maori and history, with a particular passion for ensuring historical events significant to Maori were properly documented.
He also made his voice heard by writing several books, and columns in The Listener magazine for nearly 20 years.
Green Party co-leader Metiria Turei said Dr Walker was held in "huge esteem" throughout New Zealand and by many in the party.
"I have been on many panels with Ranginui and he has always been open to a fiery debate," she said. "He was incredibly well informed, highly opinionated, and always willing to have an open conversation.
"As a Maori activist lawyer, then politician, I have always had a lot to learn from listening and watching kaumatua like Ranginui Walker.
The Green Party and I will miss him.
"Dr Walker wrote that the quest for a fair partnership under the Treaty was 'struggle without end'. Despite his passing, his work in helping to bring new generations together in a better understanding of that partnership endures."
Labour MP Grant Robertson tweeted: "Deeply saddened to hear of the passing of Ranginui Walker. A dignified, humble and committed scholar and a leader. Moe mai ra e rangitira."
Singer and documentary maker Moana Maniapoto posted on Twitter: "Incredible legacy & staunch to the end. Ka whawhai tonu ake ake. Ka Nui Te Aroha."
She added: "Spoke to him recently. Clear, consistent & utterly committed. Never wavered. Intellectual great, true warrior."
Media commentator Russell Brown tweeted: "I'm of a Pakeha generation for whom Dr Walker 'was' our view of Te Ao Māori. I feel shattered by his passing."
