What's the job?
"A plumber" is really six different jobs with six different price logics. Emergencies are a callout fee against the clock. Drains are a cheap unblock or an expensive discovery. Hot water is a four-figure replacement with some published prices. Gas is restricted work, quote only. Pick the job first: each stream has its own providers, its own prices, and its own Christchurch rules.
Emergency
Burst pipe, sewage backing up, flooding, no water. You pay a premium to have someone at the door tonight, so know your toby and know what the callout fee covers.
Drain unblocking
A gully trap overflowing or a toilet that will not clear. Jetting or rodding fixes the symptom; a camera finds the cause. Recurring blockages in quake-affected suburbs can be cracked pipes, not just roots.
Hot water
Cylinder repair or replacement. Christchurch has a cylinder specialist publishing real prices, and cold Canterbury winters make this the appliance you notice most.
Leak repair
From a dripping tap to a hidden leak inside a wall. Visible leaks are a standard-hours booking; hidden ones go to leak detection specialists, and one Christchurch firm runs a dedicated detection team.
Gasfitting
Gas hobs, gas hot water, new connections, gas leak repairs. Legally restricted work: only PGDB-registered gasfitters can do it, and none of them publish prices.
Bathroom renovation
Rough-in, fit-off, and the plumbing behind the walls. Christchurch guides put a full but basic bathroom renovation around $15,000–$22,000, with layout changes moving the number fast.
Not sure which job?
Water actively spreading, a burst pipe, or sewage coming up through a floor drain is an emergency: turn the water off at the toby and call. A slow drip under the sink or a damp patch on a wall is leak repair, and it will be cheaper booked in standard hours.
No hot water is usually the hot water stream, but check first: cold pipes into the top of the cylinder point to an electrician, not a plumber. One blocked toilet is drain unblocking; several fixtures backing up at once means the main drain and a camera.

| Gasfitting | Quoted per job, restricted work | Quote-based | Gas hobs, gas hot water, new connections |
| Bathroom renovation | Fixed price per project | $15k–$22k+ guide | Full refresh or layout change, walls open |
Christchurch rules that change the job
Most of this work is legally restricted. Sanitary plumbing, gasfitting and drainlaying are restricted work in New Zealand: they must be done or supervised by someone registered and licensed with the Plumbers, Gasfitters and Drainlayers Board. Search the public register at pgdb.co.nz before you book, and ask what certification paperwork you will receive.
The earthquakes changed the drains. The 2010-11 Canterbury earthquakes cracked and displaced underground pipes across the eastern suburbs, and ground movement still shows up as recurring blockages and bellied drains in places like Avonside, Dallington and Bexley. A drain that blocks again within months in these areas is a camera job, not another jetting.
Canterbury winters punish hot water systems. Christchurch gets real frosts, and a cylinder sitting in an uninsulated garage works harder from June to August. Exposed pipes on south walls and in roof spaces should be lagged; burst pipes from freezing are uncommon here but frost protection is cheap insurance.
Know whose problem it is before you pay a callout. Water supply and the wastewater network on the public side of your boundary belong to Christchurch City Council. If neighbours have no water either, or sewage is surfacing on the street, check with the Council first; everything on your side of the boundary is yours.
New subdivisions, new pipework. Much of Wigram, Halswell, Rolleston and Lincoln is post-quake new build with modern plastic pipework and mains pressure cylinders. Repairs there are usually straightforward; the older character stock in Fendalton, Merivale and St Albans is where galvanised pipes and earthenware drains still hide.
