Museum staff in Germany have acknowledged the passing of Mauriora Kingi and placed his portrait beside a whare in remembrance.
Mr Kingi was pivotal in the co-operation between the Hamburg Museum of Ethnology, which is the caretaker of whare Rauru.
Museum director Professor Wulf Kopke said he and museum staff felt they had "lost a friend and cousin".
In August 2011 he and fellow museum employee Dr Jeanette Kokott reached out to Mr Kingi for advice and guidance about whare Rauru's centenary in Germany.
"It was given wholeheartedly, humbly and wisely and formed the basis of a co-operation marked by respect, trust and friendship," Professor Kopke said. "As caretakers of whare Rauru we owe much to him and cherish his memory. Knowing him, his dedication, subtle humour and diplomatic ways was a privilege for us.
