The HDT Calais, a performance-enhanced version of the Holden Calais, represents a golden era of Australian muscle cars. A limited number of these vehicles made their way to New Zealand between 1984 and 1985, instantly becoming highly desirable. Owning an HDT Calais in NZ today is a commitment to preserving a piece of Australian motoring history.
Common problems with the HDT Calais in New Zealand include rust (particularly in areas prone to corrosion), engine issues (due to age, hard driving, and potential neglect), transmission problems (especially with the Turbo 700 automatic), suspension wear, and electrical faults. Authenticity is also a major concern, as some cars may have been modified or had non-original parts fitted. Sourcing genuine HDT parts can be difficult and costly.
WOF tips
When presenting an HDT Calais for a WOF in New Zealand, concentrate on rust inspection. Ensure the engine is running smoothly and that exhaust emissions are within acceptable limits. The brakes must be in excellent working order, capable of handling the car's performance. Pay close attention to the suspension components, as worn suspension can significantly affect handling. Ensure all lights and electrical systems are functioning correctly.

Rust, engine problems, and wear and tear on mechanical components are common concerns for owners in New Zealand.
