The Story so far..

Discount Drainage Ltd is a small family owned and operated Drainage company based in North Canterbury, servicing the wider Canterbury region.

Owned and Operated by a Father and Son Team - Aubrey and Leigh Tuuta

Aubrey is a Certifying Drainlayer and has over 30 years experience in drainage.

Starting his drainage career working in Picton and Blenheim on council owned infrastructure and Subdivision construction 


Aubrey has extensive knowledge in Project Management and Supervision of Drainage crews. He has held roles as Supervisor on many projects including the Pegasus Subdivision, Ashburton Business Park, Spring Creek Pressure Sewer Upgrade, Greymouth Sewer and Stormwater Separation Project and lead a crew on the Scirt Rebuild of Earthquake damaged horizontal infrastructure in Christchurch. 

Leigh is a Registered Drainlayer with 10 years of drainage experience and started his drainage career working under the supervision of Aubrey, in the Scirt Christchurch Horizontal Infrastructure rebuild. This lead onto the Greymouth Sewer and Stormwater Separation project. 

Whilst working in Greymouth and away from their families most weeks. Aubrey and Leigh decided to go out on their own.

Purchasing Discount Blocked Drains, they changed the name and started Discount Drainage Ltd in March 2014. 

Where to now? 

Discount Drainage currently have a wide range of clients including Housing companies, Insurance Companies, Builders, Large Civil Construction Companies, Subdivision Developers, Property Managers and of course homeowners. (but we're always looking for more)


We work closely with The Earthquake Commission, Southern Response and some of Christchurch's most successful Property Developers 

As the business has evolved we have upgraded plant and Equipment to suit our needs.

Plans are to continuously upgrade and modernise the fleet, for efficiency and reliablilty. 

We train and upskill our staff, to keep up with new technoligies, Health and Safety Compliance and NZ building Code Rules.  

Its not all about work!  


Aubrey, Leigh and their families, share a love of fishing and diving or just being on the water.

When they're not working on drains you'll most likely find them down the local river mouth with their whitebait or flounder net or out in their boat, catching groper, bluecod, kingfish, or diving for crayfish or paua.
