Concerns were raised within the New Zealand police about staffing changes that have taken specialist officers away from crime investigations, documents leaked to the Herald show.
Officers in the Eastern Police District raised serious concerns about the impact of removing Scene of Crime Officer (Soco) positions, according to the documents.
The draft papers are draft submissions to an official consultation process in September, and come after the Herald revealed more than 90 per cent of the country's burglaries went unsolved last year.
While the reported number of the crimes has steadily declined in recent years, so did the rate at which they were solved - falling to 9.3 per cent last year.
Socos are specialist trained investigators who gather evidence - including forensics - from crime scenes, and play a crucial role in solving crimes like burglaries. They work with the less specialised Tactical Crime and Investigation Support units.
