Optimum Plumbing Gas and Heating now offers Plumbing, Gasfitting and Heating services to the Outer islands from Auckland which include; Great Barrier Island, Kawau and Rakino Island.


Over the last year we have attended various Plumbing & Gasfitting jobs within the Hauraki Gulf. Therefore, have decided to expand this service due to the demand of technical maintence plumbing issues/service work and a severe shortage of gasfitting services on the islands.

We have extensive knowledge in all plumbing and gasfitting systems throughout and specialize in 240v and 12v gas appliances which are used widely across the islands to save on electricity usage.

If you are looking for a Certifying Plumber and Gasfitter on Rakino Island, Kawau Island or Great Barrier look no further! We have you covered. Call Robb today on 021 168 4913 to discuss your needs.

I would like to thank Rob from Optimum Marine Gasfitting for the superb workmanship and service he provided upgrading our gas system in our 70ft yacht before going offshore. His attention to detail was amazing and provided us with quality appliances that look sure to last the distance. We now feel comfortable with our gas system. Would recommend to any boat owner!
