Before you hire a drainlayer in South Auckland

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.

The questions below are drawn from 248 customer reviews collected for this page.

How much does it cost to unblock a drain in New Zealand?

Installer-published Auckland prices start at $285 plus GST for the first hour when a jetter truck is needed, then $210 plus GST for each hour after. A stand-alone CCTV drain inspection runs $250 plus GST for up to one hour.

After-hours or emergency call-outs are published at $550 plus GST. Adding 15 percent GST, that first-hour rate becomes $327.75 in your hand.

Does a drainlayer need a licence, and who pays when a drain is blocked?

Laying, altering, repairing, opening up or renewing a private drain, and fitting a gully trap or connecting to a septic tank, is drainlaying under the Plumbers, Gasfitters, and Drainlayers Act 2006 and 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. The PGDB registers three licence classes: restricted, drainlayer, and certifying, and keeps a public register you can check.

Clearing a blockage is not named in the Act's definition of drainlaying, and any repair a camera finds during a job is restricted work requiring a licensed person. In Auckland, Watercare says owners are responsible for pipes on their side of the point of supply, and asks you to call Watercare first before booking a tradesperson; for other cities, check with your local council or water utility. In a rental, tenants must tell the landlord straight away about anything needing repair, 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?

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 an underlying fault such as tree roots, a cracked pipe, or a sunken joint. Reviewers placed real value on operators who used a CCTV camera, showed or sent the footage, and gave an honest verdict on whether a clean was enough rather than pushing straight to a repair. Asking to see the footage yourself before agreeing to anything beyond unblocking is the clearest way to know what you are actually paying for, and several reviewers also appreciated being told plainly what not to put down the drain to avoid the same problem returning.

What are the warning signs of a drain company to avoid?
  • –A phone estimate that grows once the operator is on site, with no clear explanation of what changed.
  • –A hard sell on relining or pipe replacement without showing you the camera footage first.
  • –A blockage that returns within days and the company is slow to respond or charges again for the same fault.
  • –Mess left around the gully trap or garden after the job, which several reviewers flagged as a clear sign of a rushed finish.
  • –After-hours rates that are only mentioned on the invoice, not before anyone is sent out.
  • –Repeated scheduling failures or technicians arriving unprepared, which cost one reviewer three separate days off work.
What should you ask a drainlayer or drain unblocker before they start?
  • –Is the price fixed or hourly, does it include GST, and exactly when does the clock start.
  • –Is a water jetter included in that price, or is it charged on top if the blockage needs one.
  • –Is a CCTV inspection included, and will you be shown or sent the footage before any repair is agreed.
  • –If the camera finds damage, who on the crew holds a current practising licence from the Plumbers, Gasfitters and Drainlayers Board (PGDB) to do that repair work.
  • –What happens if the blockage returns within a short period, and is there any callback guarantee.
  • –For an urgent or weekend job, what is the after-hours rate, confirmed before anyone is dispatched.
