De Wattignar's next role saw him take on a New Zealand government secondment with the United Nations in Syria. During the nine months he was based in Syria, de Wattignar investigated war crimes and the use of chemical weapons in the country.
Following his overseas secondment, de Wattignar returned to New Zealand and the police in 2018 to take on a new task covering a large portion of the North Island.
"In November 2018, I began a secondment as district commander in the central district. I now have 800 staff in policing services on behalf of 365,000 citizens across a very large geographical area," he said.
"Obviously I am keen to continue with our aim of providing an efficient police service that's based on results. I firmly believe in a proactive approach to crime and crash prevention which in the end helps reduce offending and victimisation, creating happier, safer communities."
De Wattignar was permanently appointed as district commander last month.
"I am very much looking forward to meeting the community I will be serving," de Wattignar said.
"I am based in Palmerston North, but will spend time in the wider central area while on duty and off duty too."
The central district policing area includes Taranaki, Whanganui, Ruapehu, Manawatu, Horowhenua and Tararua.
De Wattignar takes over the position from Sue Schwalger who was appointed in 2014. Schwalger is now an assistant commissioner.
