Established in 1998, originally as Hamer Technology Limited, the business was sold to one of the founding staff members in August of 2004. HV Diagnostic Services Ltd continues to provide a range of independent high technology condition monitoring services for the High Voltage industry. We were first to introduce a commercial PD Testing service in New Zealand and can rightfully claim more experience in this specialised field than anyone else.
