The Nelson officer becomes the 34th name on the roll, which recognises police officers slain on duty.
The roll is read annually on Police Remembrance Day on September 29 - the feast day of the police patron saint, Archangel Michael.
Serving, retired and former police staff who have died in the past year would also be recognised at services up and down the country.
The Police Commissioner Richard Chambers and the Police Minister Mark Mitchell were expected to attend a service at Fleming's home station in Nelson, while a national service would be held at the Royal New Zealand Police College in Wellington.
Police said Constable Matthew Hunt, who was posthumously awarded the New Zealand Bravery Decoration last year, would also be recognised.
Hunt was fatally shot during a routine traffic stop in West Auckland in 2020.
Police said the national service would also remember police colleagues in Australia and the Pacific who had been killed by criminal acts while on duty, or had died as a result of their duties.
Wreaths would be laid at the New Zealand Police war memorial and recruits would perform a haka, police said.
