Plumbing Services
From dripping taps and leaking pipes to full bathroom plumbing fit-outs, Matt handles the complete range of residential plumbing services across Christchurch. With over 30 years of hands-on experience, every job — big or small — is completed to the highest standard and backed by a Master Plumbers guarantee. Whether you’re dealing with a burst pipe, or just need a new toilet installed, you’ll always deal directly with a licensed professional, not a subcontractor.

As a certified gasfitter in Christchurch, Matt is fully licensed to install, repair, and certify gas lines, gas hobs, gas heaters, and gas hot water systems for both residential and light commercial properties. Gas work in New Zealand must be carried out by a registered gasfitter — attempting DIY gas work is illegal and dangerous. When you book Integrity Plumbing, you get a qualified gasfitter who will complete all work safely, issue the required certificate of compliance, and ensure your appliances meet NZ gas safety standards.
Planning a bathroom renovation in Christchurch? Matt manages the complete plumbing side of your bathroom remodel — from relocating waste pipes and installing new shower bases to fitting freestanding baths, vanities, and heated towel rails. Having a single licensed plumber and gasfitter handle your renovation saves time, reduces coordination headaches, and ensures all work is completed to code. Matt has completed dozens of bathroom renovations across Christchurch and can work alongside your builder or tile layer to keep the project on schedule.

Christchurch’s water supply can contain chlorine, sediment, and other impurities that affect taste and long-term appliance health. Matt supplies and installs whole-house water filtration systems and under-bench drinking water filters, giving your household clean, great-tasting water straight from the tap. All systems are professionally plumbed to NZ standards and use quality filter media with easy annual cartridge replacements. If you’re on tank water or a rural supply, Matt can also advise on the right multi-stage filtration setup for your specific water quality.

Is your hot water cylinder leaking, failing to heat properly, or simply at the end of its life? Matt provides prompt hot water cylinder replacement and installation across Christchurch, typically completing the swap in a single visit. He works with all leading brands and can advise on the right cylinder size and type for your household — whether that’s a standard mains pressure cylinder, a low-pressure system, or an upgrade to a heat pump hot water unit for better energy efficiency. All installations come with a certificate of compliance and are covered by the Master Plumbers guarantee.
The Rinnai Infinity is New Zealand’s most popular continuous flow gas hot water system — and for good reason. Unlike a traditional cylinder, it heats water on demand, so you never run out of hot water and only pay to heat what you use. Matt is experienced in the full Rinnai Infinity range and can advise on the right model for your household size, gas type (natural gas or LPG), and hot water usage patterns. Whether you’re upgrading from an old cylinder or replacing an existing Rinnai unit, installation is completed to manufacturer specifications and all required certifications are issued on completion.
