A lecture about adventurer Sir Edmund Hillary's legacy has been cancelled because of a dispute between his children and the Auckland War Memorial Museum.
Sir Edmund's son Peter Hillary is seeking a High Court ruling on part of his father's will which bequeaths papers and other items to the museum.
The lecture by former Commonwealth Secretary-General Sir Don McKinnon was to have been held at the museum on Wednesday and was to discuss Sir Edmund's legacy.
But the Museum Circle, which organised the event, said the topic may have raised contentious issues relating to the dispute.
Chairperson Chris Devereux said he wanted to respect comments by Prime Minister John Key that the parties be given space to sort out their differences.
