Before you hire
Laying, altering, repairing or opening up a private drain is restricted work: it must be done by someone holding a current practising licence from the Plumbers, Gasfitters and Drainlayers Board, or under the supervision of one, and there is no exemption for householders doing it themselves. Clearing a blockage is not named in that list, but a cracked or collapsed pipe found on the camera is, so ask to see the CCTV footage before you agree to a repair.

Before you hire a drainlayer in Christchurch
Drawn from 564 customer reviews collected for this page. The first answer is what it costs.
How much does it cost to unblock a drain in New Zealand? expand_more
Installer-published prices for drain unblocking start around $285 plus GST for the first hour when a jetter truck is needed. A second hour runs around $210 plus GST, and some operators include a CCTV camera inspection at no extra charge.
After-hours or emergency call-outs are priced higher, with one published rate at $550 plus GST. These figures exclude GST at 15 percent, so a $285 plus GST first hour works out to $327.75 in your hand.
Does a drainlayer need a licence, and who pays when a drain is blocked? expand_more
Laying, altering, repairing, opening up or renewing a private drain is drainlaying under the Plumbers, Gasfitters, and Drainlayers Act 2006, and it must be done by someone holding a current practising licence from the Plumbers, Gasfitters and Drainlayers Board (PGDB), or working under the supervision of one. Clearing a blockage is not named in that definition, but any repair a camera reveals is restricted work requiring a licensed person.
The PGDB registers restricted, drainlayer and certifying drainlayers and keeps a public register you can search before hiring. On who pays: the council owns and maintains pipes up to the point of supply, and in Auckland, Watercare asks you to call them first before contacting a tradesperson, as the blockage may be on their side.
For other cities, check with your local council or water utility, as arrangements differ. In a rental, tenants must notify the landlord immediately, and careless damage is capped at four weeks rent or the landlord's insurance excess, whichever is lower.
Is a blocked drain a quick unblock, or a sign the drain needs repairing? expand_more
A one-off blockage from fat, wipes or hair is usually cleared in a single visit, but a drain that keeps blocking, gurgles, smells or backs up at the gully trap often points to something structural like tree roots, a cracked pipe or a sunken joint. A CCTV inspection is how that underlying fault is found, and reviewers specifically valued being shown or sent the footage so they could see the problem before agreeing to any repair. Honest operators in the reviews told customers when a jetting clean was genuinely enough, and several gave advice on what not to put down the drain to avoid a repeat call-out.
What are the warning signs of a drain company to avoid? expand_more
- –A job that seemed straightforward was charged at $287.50 for 15 minutes of work, with no response when the customer queried the bill, which points to pricing that was not explained before the visit.
- –Watch for a warranty as short as one week on jetting work, with a full-price call-out charge if the drain blocks again within weeks.
- –Be cautious if a company pushes a repair or relining without showing you the camera footage first, as you have no way to verify the fault is real.
- –Subcontractors used without disclosure created problems in at least one case, where the original operator had no leverage to get faulty work corrected.
- –Repeated unanswered calls, ignored emails and no-shows on a confirmed booking date are patterns that appeared in multiple negative reviews.
- –After-hours rates not stated before anyone is dispatched can leave you with a bill well above what you expected.
What should you ask a drainlayer or drain unblocker before they start? expand_more
- –Ask whether the price is fixed or hourly, whether it includes GST, and exactly when the clock starts.
- –Confirm whether a high-pressure water jetter and a CCTV inspection are included in the quoted price or charged separately.
- –Ask whether you will be shown or sent the camera footage before any repair is agreed to.
- –If a repair looks likely, ask which crew member holds a current practising licence from the Plumbers, Gasfitters and Drainlayers Board, and check the public register.
- –Ask what the call-back policy is if the blockage returns within weeks, and get the warranty period in writing.
- –For an urgent or after-hours job, ask for the after-hours rate before anyone is dispatched, not after the work is done.

How are the top drainlayers & drain unblockers in Christchurch chosen? expand_more
We build this page from Google Maps results for drainlayers & drain unblockers in Christchurch. Each one is scored on its public rating and review record. Businesses outside the area, or whose reviews describe a different line of work, are left out, and a business whose main Google category is a different trade is held back until a person has checked what it does. A business whose website no longer resolves and that has had no Google review for six months is treated as dormant and left off the page until either changes. Every category and city is rechecked on a rolling cycle, about every two to three months. A location with a subscribing business is rechecked every month, and the whole page updates with it. See how we rank for the full method.
