Dempster and Hill are your power tools testing and tagging specialists. Unsure of whether you need testing and tagging? If you have anything electrical with a cord, and it’s in a commercial or public environment – you need us. 

Health and Safety New Zealand regulations specify that all commercially used power tools must be tested and tagged. We offer testing and tagging to contractors, builders, plumbers and roofers. We can test anything with a power cord.

We can also offer testing and tagging of equipment and appliances for schools, retirement homes, university boarding dorms and other shared accommodation.

We offer an emergency breakdown service ensuring your emergency gets dealt with promptly, and minimises downtime, or protects those parts of your business that relies heavily on electricity, including chillers, or power supplies to technology. Call us, 24/7 and we will be there.
