Kawerau's water boil notice has been lifted after samples of water came back clear of contamination over the last three days.
The Kawerau water supply was tested for E. Coli contamination on Sunday and yesterday, which both came back clear.
The third test from the sample point also came back free of E. Coli contamination today.
The next round of scheduled tests from four different sites across the water supply has also come back clear of contamination.
Kawerau residents were told to boil drinking water due to E. Coli on Saturday.
