“Caution” was advised after tests done in Hangaroa River at Doneraille Park.
Testing early this month at Sponge Bay, Tūranganui River, Wainui and Wherowhero Lagoon at Muriwai came back OK for swimming.
On the East Coast, swimming is OK following tests at Pouawa, Tokomaru Bay and Waipiro Bay.
However, caution was advised for Mangahauini River in Tokomaru Bay, the surf club and wharf end of Tolaga Bay, Wharekahika and Urukokomuka Stream.
Several sites on the Coast were deemed unsuitable for swimming — Anaura Bay's north lagoon and north and south camps, Makarika Stream, Hamanatua Stream at Okitu, Turihaua, Uawa River and Waiapu River.
The Waipaoa River testing site result also came back as unsuitable.
