EQC & earthquake damage drainage repairs.
EQC is now known as the Natural Hazards Commission (NHC).
Christchurch's drainage systems were hit hard by the earthquakes. Much of the existing drainage is earthenware, never designed to withstand this kind of ground movement. A CCTV inspection is the only reliable way to check the true condition of underground drainage, and many properties still carry hidden damage that's never been camera-checked.
We handle the technical side of NHC drainage repairs, from CCTV assessment through to completed repair, with the same standard of work whether the job is covered by NHC, another insurer, or paid for privately.
Earthquake & EQC repairsLeft unchecked, hidden damage can lead to:
Health risks to your family- Environmental contamination of soil and waterways
- Worsening damage over time
Not sure where your property stands? A CCTV inspection gives you a definitive answer, and solid footage for NHC or insurance purposes.
The jobs other drainlayers walk away from. We don't.
Post-earthquake drainage, shared driveways, cross-lease sections and collapsed pipes are where we've built our name. We put a camera down first, work out what will actually last, and give a blocked home drain the same care as a subdivision.
Done right first time
No coming back twice
Left tidy
Property reinstated properly
Fair and up front
A clear price before we start

Real reviews from real Christchurch jobs, names and all.
Read all 38 reviews on Google“I had dealings with four other drainage companies before contacting Smart Contracting, but it was Mike who came up with the practical solutions to sort the post-earthquake problems of two townhouses and a common driveway. Thank you for making the whole exercise so painless and effective.”
“A drainlayer had gone so deep with the pipes it destabilised our house piles. So close to Christmas, who was there to fix it? Bryden, Mike and team came to the rescue, understood the scope, dug it all out, re-stabilised the soil and put the drains back in. A truly superb job, and slightly under quoted cost.”
“Job completed to a very high standard. Really great, easy communication all the way through. Experienced advice for an alternative system to save damage. Respected the property and reinstated to a high standard. Many thanks to Mike and the team.”
“You'll be in safe hands with Smart Contracting. The team were excellent from start to finish, delivering great service and a great result. I recommend them highly.”
Camera first, no guesswork
We find the problem before we dig.
A lot of drainage money gets wasted digging in the wrong spot. We put a camera down the line first and see exactly what is going on, a blockage, tree roots, a cracked ceramic pipe or earthquake damage, and how far down it sits. Then you get a straight explanation and a fair price before anything is dug up.
- See the real fault on camera
- No digging up the whole yard
- A fair price agreed up front
- Footage for insurance and EQC

Common questions.
Who do I call for a blocked drain in Christchurch?
Smart Contracting handles blocked drains across Christchurch and the wider Canterbury area, sinks, toilets, gully traps, the lot. We find the blockage, clear it, and let you know if there's an underlying issue worth sorting while we're there.
Do you do earthquake and EQC/NHC drainage repairs?
Yes, this is one of our specialties. EQC (now the Natural Hazards Commission, NHC) is required to be officially notified before we begin, so give them a call and have Smart Contracting nominated as your contractor. From there, we carry out a full CCTV and drainage assessment, then provide a repair proposal and costing.
Are you certified drainlayers?
Yes, our team is fully certified and CCC Authorised Drainlayers. Every job is done to code and to a high standard, whether it's a small residential repair or larger civil works.
What areas do you cover?
We cover Christchurch and wider Canterbury, including Rolleston, Halswell, Hornby, Cashmere, Riccarton, Wigram, and West Canterbury.
How does pricing work?
We assess the job first, usually with a CCTV inspection where needed, so you get an accurate, honest price before any work begins. No guesswork, no surprises once we start digging.
Do you use CCTV before starting repairs?
Always, where it's relevant. A camera down the line shows us exactly what's going on underground, so we're fixing the actual problem rather than guessing. This also gives you solid footage for insurance or EQC/NHC purposes if needed.
Will you leave my property tidy?
Yes, reinstating the property properly is part of the job, not an afterthought. We treat your section the way we'd want ours treated.
