our family values

You could say that Plumbing runs in our blood. Plumbing has been part of the MacMillan family history since the 1930’s with Grandad Alec Charles Stewart MacMillan was the original OG Plumber and one of only 20 people to achieve a National Life Member award for Master Plumbers. An amazing accomplishment for an organisation that has been in existence since 1901.

Bruce and Jeni MacMillan and have been steering the ship since the 1970’s in between the fondue and bowls parties and now Rohan MacMillan is based in the Auckland office, and Angus MacMillan is based in Christchurch office.

why trust us?

We are still part of the Master Plumbers that our Grandfather joined in 1930. Things have drastically changed since then! But we truly believe it is paramount to be part of an organisation which helps maintain an incredibly high standard in the industry. Because we are members of the Master Plumbers Association, it gives our clients even more peace of mind as their guarantee is a 12-month guarantee and up to $15,000.

We have extensive experience in the industry with our skilled team of 51. We employ 4 new apprentices every year.
