If you notice a water leak on a road, in a park or reserve, or on someone else’s property please let us know – giving as much information as possible about the leak (e.g. location, size). If the leak is on private property, we'll get in touch with the land owner to get it fixed.
Some leaks require urgent attention, while others can be fixed under normal response times. Please call us on 06 759 6060 or email us.
Leaks on the property side of the meter or water toby are the responsibility of the property-owner to fix, while NPDC is responsible for fixing leaks on the road-side of the meter or water toby.
If your toby/manifold is leaking, try to establish where the leak is coming from. If the leak comes from the pipes or fittings inside the toby/manifold box or from the street side of the toby/manifold box, you should contact NPDC to report it. If the leak is on the pipe on your property side of the toby/manifold, or there is a leak elsewhere on your property, you will need to contact a plumber for assistance and advice.
You can check if you have a leak on your private line or on NPDC's line by checking your water meter. Take a reading of the meter in the evening and another in the morning, ensuring that no water is used overnight. An increase in the reading overnight indicates that water has passed through the meter, and that there is a water leak on your side of the meter, in which case you should contact a plumber for assistance/advice.
Your meter might also display a flag icon, which indicates you might have a leak.
If you are physically unable to check the meter, please contact NPDC and our Green Plumber will investigate whether your property has a leak.

NPDC will send you a letter if your property has had a continuous flow of water for at least 14 days (including overnight, when households usually don’t have water use). You can either check your meter to confirm that there’s a leak (see the Q&A above for details) or call in a plumber to confirm.
You will also need a plumber to locate and fix the leak.
It can take up to 20 days for a leak flag to stop displaying even when a leak has stopped. You can always double-check by taking a reading of the meter in the evening and another in the morning, to see whether no water was used overnight.
Water mains refreshing, or flushing, happens when we open up hydrants for up to 20 minutes to run fresh water though pipe networks that are not frequently used (e.g. in cul-de-sacs and dead end roads).
This sometimes causes water pressure to drop, however it seldom drops below the minimum level we've set.
