Our Story
The Neill Group (TNG) was founded by Dion Neill. Dion is a former member of the New Zealand defence forces and emergency services (qualified first responder). In the 1980s, Dion served his apprenticeship with a team of former police officers, military personnel and intelligence officers. He was trained in every aspect of conducting investigations and surveillance.
Since then he has clocked up years of experience managing undercover operations and investigating dishonesty offences. Dion is a strong advocate for raising the level of professionalism and service delivery within New Zealand’s security industry.
Dion was one of the first private investigators to carry out assignments for the Accident Compensation Corporation (ACC). In 1997, Dion was certified as a fraud examiner and gained a Certificate in Investigation Skills from the private training establishment of the Royal New Zealand Police College.
Dion is regarded by the New Zealand Courts as an expert witness, he provided evidence in the High Court relating to a lengthy theft investigation. Dion’s evidence was instrumental in securing over 20 convictions. Dion featured on the television series, ‘Private Investigators’. He was also interviewed on TVNZ Breakfast regarding protecting high profile people in New Zealand.
Dion has also been awarded with a Certificate in Security Operations to Level IV (Australia), Diploma of Security and Risk Management (Australia), along with a number of other internationally recognised credentials.
