At first, police told the authority the officers lawfully entered Ms X's home under section 14 of the Search and Surveillance Act 2012. Police said they had reasonable grounds to suspect a risk to the life or safety of Ms X that required an emergency response.
"We independently investigated Ms X's complaint. We found, and police now accept, that the officers unlawfully entered Ms X's home," the report said.
The officers did not have the necessary information to form a reasonable suspicion that Ms X's life or safety was at risk and that they needed to urgently respond, which would justify a warrantless entry under section 14 of the Search and Surveillance Act 2012.
No other power made their entry lawful.
The authority also found the police staff involved were ill-equipped to effectively respond to mental health crises, despite being routinely called upon to do so.
Authority chairman Judge Colin Doherty said the officers did not have substantive information indicating Ms X's life or safety was at risk.
"Their perceptions were coloured by the fact they are often asked to respond to suicide and self-harm incidents," Doherty said.
"Those incidents remained fresh in the minds of the officers. Although the actions of the officers were unlawful, they were not uncaring."
Bay of Plenty District Commander Superintendent Tim Anderson said the officers had genuine concern for the woman.
"Given that, they entered the home based on what [was] unfolding at the time, the information they had available and their past experiences," Anderson said.
"Police officers go to work every day to keep people safe, and part of this work does involve complex incidents where people are in potential mental distress.
"In these instances, we enable our people to make the best decisions possible, with the information they have at this time, to ensure peoples' safety and wellbeing."
