Kia ora! Please note that we are experiencing some delays. You can still request a testing kit now and it will be posted out to you. However, we won’t be able to test any returned samples until the end of July 2024. Thank you.

Free mail-in nitrate water testing

For drinking water from private bores

Everyone should be able to trust that the water from their tap is safe to drink.

We’re offering free, mail-in water testing so you can check your water for nitrate contamination linked to bowel cancer and preterm birth and caused by synthetic nitrogen fertiliser and too many cows.

If you rely on bore water for your household supply, you can order a free mail-in nitrate water testing kit here:

  1. Fill in this form with your contact details and some additional information (one sample per form)

  2. Let us know if you consent to your data being used confidentially by researchers*

  3. We will send you a water sample kit including container, instructions, and a prepaid courier envelope for returning your sample to us  

  4. When your kit arrives take a sample of unfiltered water from your tap and please send it to us on the same day

  5. We will test your water for nitrate and contact you with the results.

 

*Information from testing results is important to researchers including those at Otago University who want to better understand nitrate contamination. If you consent, we will confidentially share your data with researchers.

Success!

We have received your request and we’ll post out your sampling kit as soon as possible. The kit will include a water sample container, instructions, and a courier envelope to send the sample to us for testing.

We also want to offer this service to other people on bore water. Will you help spread the word?
