Police extend their sympathies to the families of the victims.
Ms Paul is believed to be the same woman facing sentence on charges relating to the Ohakune manhunt last year.
She had pleaded guilty to being an accessory after the fact to attempted murder and helping Dolphy Kohu avoid arrest after shooting at police officers.
She also pleaded guilty to unlawfully taking a motor vehicle.
At an appearance in court last year, Ms Paul and Mr Kohu stood in the dock together hugging and kissing.
Mr Kohu died in prison in January.
Police would not confirm whether it was the same Hereina Paul.
