The more serious charge of manslaughter was levelled on the advice of a Rotorua crown solicitor, who told police it was warranted.
The officer leading the investigation, Detective Senior Sergeant Todd Pearce, says it was right for police to seek further advice about the charge.
"The circumstances of Ms Ives death were different from what police normally deal with in most hunting related incidents and deaths, so it was important that additional advice and review was sought," Mr Pearce said.
"It is also appropriate that we consider the legal advice we receive, and act on it as we have in this instance."
The NZ Deer Stalkers Association had been pushing for Mears to be charged with manslaughter, to set an example to others.
