Field agents

A personal visit by a professional field agent is a proven method to ensure compliance with legal and contractual obligations. Field visits can be an effective way to facilitate debt recovery. It’s harder to say no to someone when they are standing right in front of you. Our nationwide field agents and Ministry of Justice licensed repossession agents have the ability to communicate with people at every level. We have experience interacting safely with people who respond best to a personal visit, including those with addiction issues. We provide floor plan audits of motor vehicle dealerships, as well as the assessment of assets and property for major banks, financial institutions and government agencies.

We carry out field visits to confirm addresses, negotiate payment arrangements and to inspect secured assets. All our field agents are authorised by the court to serve legal documents and they are also experienced in stock audits. This involves sighting stock, collecting data such as serial and model numbers and if necessary, taking photographic evidence. A number of our field agents and private investigators are former senior police officers, their specialised knowledge and skills have uncovered theft, fraud and other dishonesty offences.

Private investigators

Our investigation team includes respected private investigators who are qualified former police detectives, senior police officers and government intelligence specialists. They know how thieves, fraudsters and cheating spouses or partners think, so they know how to catch them. Our private investigators have been catching abusers, thieves, fraudsters, online scammers and deceptive people since 1987. Dion Neill is Wellington's longest established private investigator, he is supported by an extensive network of associates in every region of New Zealand.
