Mr Harris was a staunch RSA member, was involved with the New Zealand Nuclear Test Victims Association and helped out the ATC 21 Squadron, Riding for the Disabled, and many individuals.
He was described as a devoted family man who, when he was not out helping others, could be found in his shed or garden.
On his casket were laid out his cycle helmet, gardening tools, navy service medals including a special services medal and a rather odd remnant from his life.
This was a gold-painted universal joint with the inscription "Malcolm's new knee joint" which had been gifted to him by friends as a joke after he had recovered from a very serious car crash in 1995 that shattered his knee.
Apart from his service on the HMNZS Pukaki, during the bomb-test years, Mr Harris served on other leading vessels including the HMNZS Royalist.
He was an engineer by trade.
