What to check when hiring drainage contractors in New Zealand
MyTrustedTraders ranks on independent public evidence. No ads, no paid placement. Use these checks alongside the evidence on each profile before you decide who to contact.
- In New Zealand, restricted building work must be carried out or supervised by a Licensed Building Practitioner, and all electrical, plumbing, gasfitting and drainlaying by a licensed tradesperson (EWRB for electricians, PGDB for plumbers and gasfitters). Check the public register before you hire.
- For residential building work of $30,000 or more you are legally entitled to a written contract and a disclosure statement setting out the tradesperson's skills, licences and insurance. Ask for both before work starts.
- Confirm they cover your area and can actually come out in your timeframe before anything else.
- Read recent reviews for reliability and turning up on time, not only the quality of the work.
- Agree the call-out fee up front, and be wary of large upfront deposits for an emergency job.
How to judge a drainage contractor
Independent, no-ads guidance. The trade-specific checks that matter most, the warning signs, and what to ask before you hire. Use it alongside each tradesperson’s public evidence above.
Verify before you hire
- Drainage work, connecting to council stormwater or sewer, is restricted work that must be done by a PGDB-licensed drainlayer; check the licence on the PGDB register (pgdb.co.nz).
- Connecting to public drains needs council approval and an inspection, and the drainlayer should provide a Certificate of Compliance for restricted work.
- Check public liability insurance and GST registration (required above $60,000 turnover).
- Get a written scope covering the pipe runs, falls, connection point and reinstatement.
Warning signs of a cowboy
- Does drainage connections with no PGDB drainlaying licence.
- Connects to council drains without approval or inspection, or won't issue a Certificate of Compliance.
- No proof of insurance, a large cash deposit, or no written quote.
- Vague about who supervises any unlicensed workers.
Questions to ask before you hire
- What's your PGDB drainlaying licence number, and is it current?
- Will you arrange council approval and inspection, and provide a Certificate of Compliance?
- Do you carry public liability insurance?
- What warranty applies under the Consumer Guarantees Act?
Frequently asked questions
- How do I choose a trustworthy drainage contractor?
- Compare the public evidence on each profile: how many independent reviews they have and across how many named sources, the rating and how recent it is, any credential evidence, and the company status. A drainage contractor backed by several named sources is harder to fake than one found in only one place.
- Does MyTrustedTraders rank or recommend drainage contractors for payment?
- No. There are no ads and no paid placement. Drainage contractors are ranked only by the strength of independent public evidence. No one can pay to rank higher, add a badge, or change their reviews.
- Where do the reviews come from?
- They're imported from named public review sources and always shown with the source named. They aren't reviews written on MyTrustedTraders. We cross-check the same business across sources rather than creating new reviews.
- What should I check before hiring a drainage contractor?
- Confirm credentials and insurance directly with the drainage contractor, get a written quote, and run the Cowboy Checker on the business first. MyTrustedTraders helps you shortlist on the evidence. It doesn't replace your own checks before you hire.
