"City-wide sprinkler restrictions have never been necessary beyond the first week of April," Burton said.
"The length of this year's waters restrictions reflects the knock-on effect of three unusually dry summers for the Bay of Plenty which has had an impact on soil moisture and stream levels.
"While flow levels in the Tautau and the Waiorohi Streams are now stable, flow is still lower than normal. Should we experience another winter that's drier than usual, we will start next spring on the back foot making early water restrictions likely."
An education campaign will be launched later in the year, encouraging people to make every day a water conservation day. A necessary shift in mindset, Burton said.
"Water is a finite resource, of which low stream levels are a stark reminder. This means we are asking the community to continue their conservation habits when using water. It's a year-round change in attitude that will help ease the need for future water restrictions."
The construction of the Waiāri Water Supply Scheme is under way, due to be completed late in 2022, to help meet the future water supply needs of Tauranga.
