Auckland's town supply is treated and monitored, and it is safe to drink. Many households still choose to filter it, usually to remove the chlorine taste and smell, catch sediment after mains work, or give the family water they actually enjoy drinking. On tank and bore supplies, filtration is about safety as much as taste. We supply and install water filters for Auckland homes, from a single under-sink filter for the kitchen tap to a whole-house system on the main line, and we fit the replacement cartridges when they fall due.
We start with what is in your water and what you want to change, then recommend the simplest system that does the job. No sales pitch for equipment you do not need.
Pricing: quotes are free, and every job gets a fixed price before we start, so there are no surprises on the invoice.

Do you need a filter on Auckland town water?
For safety, generally no. Watercare treats the supply to New Zealand drinking water standards. For taste, smell and comfort, a filter often makes a noticeable difference, particularly to the chlorine used to keep water safe as it travels through the network.
Hardness is worth a mention. Watercare says New Zealand water, including Auckland's, is comparatively soft, though it varies with the source. Some groundwater-fed areas, such as Waiuku, are moderately hard and see more scale on taps and shower glass. A full water softener is rarely needed on most Auckland town supply.
Types of filtration we install
The right system depends on your water source and what you want to remove:
- Under-sink carbon filters with a dedicated drinking tap, for taste and chlorine
- Whole-house sediment and carbon filters, so every tap and shower is filtered
- Reverse osmosis units for the lowest dissolved solids at one drinking tap
- UV sterilisers for tank and bore water, to treat bacteria and protozoa
- Sediment pre-filters to protect pumps, valves and appliances
How It Works
Tank and bore water need a different approach
Rural and semi-rural properties in places like Kumeu, Clevedon, Dairy Flat and Waiheke often rely on rainwater tanks or bore water. That water has not been treated, so filtration is part of making it safe. Taumata Arowai's acceptable solution for roof water supplies and BRANZ guidance both point to staged treatment: first-flush diversion, fine filtration and UV disinfection.
We set those systems up in the right order, with a sediment filter ahead of the UV lamp so the light can do its job, and a clear schedule for changing cartridges and lamps. Sludge in the tank itself shortens cartridge life, so periodic water tank cleaning helps too.
What affects the cost
Larger systems cost more depending on:
- Under-sink versus whole-house installation
- Number of filter stages and the cartridge type
- Whether UV or reverse osmosis is required
- Access to the incoming main or cylinder supply
- Whether an electrical point is needed for UV units
Keeping your system working
A filter that is never changed can end up worse than no filter at all, because a clogged cartridge restricts flow and can harbour bacteria. Most domestic cartridges need replacing somewhere between every six and twelve months, depending on the cartridge and how much water you use. UV lamps typically need annual replacement.
We note your cartridge types and install date, and remind you when replacements are due. If your water pressure has dropped since the filter went in, a blocked cartridge is the first thing to check.
Why Choose Cheeky's Plumbers for Water Filters
Matched to your supply
We start with your water source and what you want to change, then recommend the simplest system that does it, from an under-sink unit to whole-house treatment.
Certificates actually checked
Where a filter carries NSF/ANSI certification, we check the certificate lists the contaminants you care about rather than taking the box at its word.
Staged treatment for tank water
On tank and bore supplies we fit sediment filtration ahead of UV, in line with Taumata Arowai's acceptable solution for roof water, so the lamp can do its job.
Cartridge reminders
We note your cartridge types and install date, and remind you when replacements are due.
No softener upsell
Most Auckland town water is soft, so we rarely recommend a water softener unless your supply genuinely needs one.
Water Filters FAQs
Is Auckland tap water safe to drink?
Yes. Watercare treats the supply to New Zealand drinking water standards. Filtration is mainly about taste, smell and sediment on town supply.
Do I need a water softener in Auckland?
Usually not. Watercare describes Auckland's water as generally soft. Some groundwater areas are harder and may benefit from scale control.
How often do filter cartridges need changing?
Typically every six to twelve months, depending on the cartridge and your water use. UV lamps are usually replaced yearly.
Can you make tank water safe to drink?
Yes, with the right combination of first-flush diversion, filtration and UV treatment, plus regular maintenance.
Will a whole-house filter reduce my water pressure?
A correctly sized system has little effect. A pressure drop usually means a cartridge is due for replacement.
What does NSF certification mean?
It means the filter has been independently tested to reduce specific contaminants under an NSF/ANSI standard. Always check which contaminants are listed.
