We are located at Shuttle Drive, Bromley, Christchurch.
Our new state of the art water laboratory is set up for microbiological and chemical testing of water supplies for both Council business and private customers.
We can customise analyses to suit your needs and recommend that you contact the laboratory before you undertake sampling to ensure the correct type of samples are taken.
Location
Testing services
Our laboratory is accredited with International Accreditation New Zealand (IANZ) and listed on the Ministry of Health’s Register of Approved Testing Laboratories for Drinking Water Supplies for a range of chemical and microbiological tests.
All New Zealand drinking water is recommended to meet the standards set out by the Ministry of Health.
The laboratory can assist with the testing of:
- Drinking water and groundwater: analysing Christchurch and surrounding district's drinking water and groundwater to ensure the safety of the supply.
- Sewage: monitoring that consent requirements are met.
- Wastewater: industrial waste testing.
- Other specialised tests for private customers.
Routine analysis is processed within 10 working days of receipt.
Interim test results for microbiological analysis of drinking water are available within 24 hours of testing, with a test report typically issued within 3 working days of sample receipt.
A surcharge of 50% applies for urgent samples required to be analysed within 3 working days of receipt.
International Accreditation New Zealand (IANZ)
IANZ is the organisation that makes sure New Zealand keeps being the kind of place we all love living in. They protect the health and wealth of New Zealand by ensuring that those who test or inspect the products and services we buy, consume, use, or are surrounded by every day are safe, accurate, and aren’t doing us harm.
They do this by ensuring testing laboratories, inspection bodies, building consent authorities and medical imaging providers meet international standards and can demonstrate that they are competent.
IANZ also helps our exporters access international markets by ensuring that those who test or inspect their products, meet the required standards for each country. Not all laboratories or inspection bodies are accredited, so when you see that our reports or certificates carry the IANZ mark of competence, you can have confidence in results that are trusted in New Zealand and around the world.
