Two women make formal complaints about Wally Haumaha

Two women have made formal complaints about alleged bullying by Wally Haumaha.

The Independent Police Conduct Authority (IPCA) confirmed to Newshub it has been notified of the complaints about the Deputy Police Commissioner, and would be investigating.

Three women involved in a joint justice project reportedly left Police National Headquarters (PNHQ) in 2016 as a result of alleged bullying behaviour from Mr Haumaha.

NZME reports the complaints were laid by two of those three women.

It's also claimed Mr Haumaha called a lower-ranking officer who intervened in a heated exchange between him and the three women in an attempt to rally their support.

An inquiry into his appointment as Deputy Police Commissioner will commence on August 20, led by Mary Scholtens QC.

Its purpose is to examine, identify and report on the adequacy of the process that led to Mr Haumaha being appointed.
