Glenn McKibbin is recorded as the 24th of 29 New Zealand police officers killed by a criminal act while carrying out their duties.
The first was in Northland in 1890 and the most recent was the slaying of Senior Constable Len Snee during the shooting of three officers by cannabis grower Jan Molenaar in Napier in 2009.
Constable McKibbin was stationed at the Flaxmere police station, where the memorial will start at 9.30am on Thursday and be attended by police along with Mr McKibbin's parents and other family members. Members of the public are also invited.
Retired Inspector Ross Pinkham, who headed the investigation, recalled it as a tragic day in which the angry Thompson, determined to "make a name for himself", saw an opportunity when he came across the officer on the street and took it.
With Thompson experienced as a soldier, it was not surprising that he had survived so long apparently in the outdoors, during a manhunt which stretched as far as Porangahau.
Communities in Hawke's Bay became used to their community officers patrolling while armed. The Armed Offender Squad was deployed on 55 of the manhunt's 65 days, while the arrival of the duck-shooting season, with its camouflaged hunters and rounds of shooting, about 10 days after Constable McKibbin was shot, added to the unnerving times.
