  • Are you a homeowner needing a small electrical job OR a major renovation? 
  • Are considering expanding your commercial premises? 
  • As a landlord do you want to keep your property assets sound? 
  • Does your business need testing + tagging undertaken?

From residential to commercial, big jobs to small, at CDI Electrical you can always expect quality work and good old fashioned service with a smile. Formed in 2013, CDI Electrical's founder Darren Calkin was first licensed with the Electrical Board in the early 90's, giving you almost 30 years of experience to rely on. 

Based out of Henderson, we serve all of Auckland (from Orewa and Hibiscus Coast down to Pukekohe and beyond) and have been known to travel out of Auckland for special projects.

Generally we work 7:00am to 5:00pm, Monday to Friday - but work outside of these hours on a regular basis, depending on the type of job being undertaken. We do offer a 24 hour callout service for urgent jobs and weekend work can be scheduled as required.    

We have no intention of being the biggest in the industry but every intention of providing the best service. We are proud to be your first stop for residential and commercial electrical work so get in touch today.

Do you have electrical issues within your house? 

Are you having renovations completed or building a new house and require an electrician? Get in touch today.


Want to save money by changing your lighting to LED lights? Is your commercial premises being renovated or do you need extra data cabling laid? Do you need extra power points to get rid of those dangerous extension leads lying across the floor? Do you have equipment that you need inspected with thermal imaging equipment? 

Thermal imaging is a quick way to identify equipment likely to fail and CDI Electrical has thermal imaging equipment onboard. For all your commercial requirements contact CDI Electrical.


Testing and Tagging involves visual inspection and electrical testing of electrical devices. Once deemed safe and compliant, the item is then tagged with an approved label.

Get smart! Ensure you, your staff and clients are safe, your site meets Worksafe NZ requirements and your electrical equipment complies with your insurance policy today.

Proudly servicing the Auckland region

"If you want a reliable friendly, trustworthy and professional electrician service Darren's your man. 

Darren offered creative solutions for our lighting needs and supplied everything, making it unnecessary to hunt around lighting shops that sometimes don't offer much help. He even gave us options to test out so we could see what we were happiest with. 

1. He turned up when he said he would. 
2. He completed the job within the timeframe he stated. 
3. His work was of a high standard. 
4. I would definitely use him again. 

Thanks Darren."
