Dion has successfully investigated hundreds of insurance claims and detected fraudulent activity by claimants.

Theft, Fraud & Dishonesty Investigations  

Fraud inside a business or organisation frequently occurs through poor internal processes, this allows a window of opportunity for people in positions of trust to carry out offending such as theft or fraud.


Drug, Alcohol & Substance Abuse Investigations   

Do you suspect your family member, partner or employee maybe using excessive alcohol, taking drugs or illegal substances? Alcohol and drug abuse is known to be the source of criminal activity and the foundation of anti-social behaviour.


Physical & Psychological Abuse Investigations 

Is someone in your life a possible victim of physical or psychological abuse? Our private investigators will provide the evidence to help protect you and your loved ones. The factual evidence provided by our private investigators are often used for the basis of a complaint to the police.


Covert Static & Mobile Surveillance  

Covert surveillance is a common element as part of many investigation services, including commercial investigations, insurance fraud investigations and the investigation of suspected infidelity (cheating partners).

Covert surveillance is a very powerful tool used in investigations where evidence is obtained in order to secure prosecutions – substantial intelligence is often gained from surveillance operations.


New Zealand & Worldwide Tracing Services 

Some people intentionally go missing because of illnesses like anxiety and depression. Others go missing when they become a victim of a crime.

Our qualified and licensed private investigators are resourceful, we use a range of proven investigative techniques like field visits along with online data mining to gather information on a person’s whereabouts.

Depending on how much information you have, and how long they have been gone, locating missing persons can be much faster than you may think.

In many cases, contacting us and making use of our networks, contacts and databases will help you find the person in question faster than you would expect.

Other cases can be more challenging – when a missing persons case is not a simple database job, it can take significantly more effort to find them, this is especially true if an individual wishes to remain hidden. We have an excellent track record of successfully locating missing people.


Trade Mark & I.P. Investigations   

We are instructed by legal firms to investigate infringements of branding, international copyright and trade mark patents along with the unauthorized use of logos and theft of intellectual property.
