Police are reviewing the rules about which officers killed on duty can be remembered on their national memorial wall.
Officers eligible include those killed as a result of the criminal intent of another person, but not those who have died in accidents such as drownings or helicopter crashes.
Constable Gregory Rowe drowned during a water rescue in Wellington in 1978, at the age of 23. His sister Nicola Barrett says he gave his life while working and the absence of his name on the wall demeans that enormous sacrifice.
Police Headquarters says the rules do not demean any officer's memory, but a discussion paper is being prepared so consultation can take place on ways to honour all those who have died on duty.
The memorial wall is in the grounds of the Police College in Porirua.
