KNZM, MBE should go in the suffix field but there might not be room enough. Sir should go in the prefix field (which Wikitree substantially ignores and deprecates). What is shown where is under “Display Names” (top right tab #2).
It is interesting that NZ has done away with what in UK is called a Knight Bachelor (eg Sir Paul McCartney cf. Sir Winston Churchill, KG) which has a prefix but no suffix. Wikitree Display Names suppress the Prefix which is a solecism. As a result of this some Wikitreers put the Sir in the Proper First Name and Preferred Name and do not put it in Prefix.
