Field Services 

We visit a client or debtor to establish their financial means and intentions of repaying debts. Examples may include third party drivers who fail to make or keep contact with insurers, debtors who ignore their responsibilities or avoid clients or companies who fail to maintain contact with suppliers after failing a scheduled payment date. On such occasions we attend and gather the relevant details and encourage debtors to either contact clients direct and reschedule payments or warn them of impending legal action.

We are not only licensed as private investigators, we are also licensed by the Ministry of Justice (PSPLA) as repossession agents. We are approved field agents and process servers for a number of responsible lenders, financial institutions and government agencies. Unfortunately, in the current financial climate, more private borrowers fall into arrears with their scheduled payments and as such the bank or other financial institution decide to repossess the goods or security property.

Our agents are sensitive to the circumstances and are well trained in conflict resolution in such cases and handle each matter with great care thus avoiding any embarrassment to the client or negative brand reputation. We aim to complete all asset repossession inquiries swiftly and easily, maintaining a high level of professionalism at all times.
