Dion is a former member of the New Zealand defence forces and emergency services. Dion contracted to a number of security and investigation company’s prior to establishing The Neill Group and Protective Services. Dion was also the founder and director of Wellington Investigations.

Dion was formally board certified as a fraud examiner, he has a number of recognised credentials in the area of security, risk management and investigations. Dion has published articles on personal safety, loss prevention, retail security and fraud prevention.

In the late 1980’s, Dion was a member of a team employed to investigate a major organised theft syndicate. As a result of Dion’s evidence, over 20 offenders were convicted in the High Court of New Zealand (Dion survived cross examination by the late Mike Bungay QC who represented the defendants).

Dion was one of the first private investigators to carry out investigation assignments on behalf of the Accident Compensation Corporation (ACC). Dion has spent over three decades conducting surveillance, managing undercover operations and focussing on the investigation of dishonesty offences. Dion’s unique skill set is also widely used to recover hidden assets and to serve documents on evasive defendants.

Dion featured on the TVNZ series, ‘Private Investigators’ and the TVNZ Breakfast show regarding protecting high profile people in New Zealand. The Neill Group has earned an exceptional reputation for providing service excellence and value through a strategic nationwide network of locally based agents and international alliance partners sourced exclusively from the defence forces, law enforcement and intelligence sectors.
