Our Testimonials

Hear what our customers have to say.

Great service. The team really know what they are doing I take a number of cars to them.

Jordan Clemence

HM Auto Electrical have done almost all our auto electrical work from Utes to trucks. Michael’s work is second to none, expertly completed and never had failures to any installations or work undertaken. He is a perfectionist and thorough where reliability is always been a mark of his. From professional wiring to compliant and safe electrical work, I am always happy to bring something over when we need it.

I had a WOF done on a small trailer today. The staff member I dealt with could not have been more pleasant. The WOF was very reasonably priced as well. I will go back and have no hesitation recommending them.

Brilliant service.I was in the area, plant shopping, after failing a WOF for a blown headlight bulb in central ChCh.I rang them... 'Any chance you could have a look at it now for me, please ?' They said they could. I rocked up and 5 minutes and $10 later including bulb and fitting, I was done.Lovely chap. Bringing old school customer service back to our chaotic world.They deserve to do well.
