A sewage spill into the Raglan's Whaingaroa Harbour has been fixed, but it is unlikely people will be able to swim or collect shellfish there for the rest of Easter weekend.
Waikato District Council staff worked through the night after the main sewer to the Marine Parade pump station collapsed at about 8pm yesterday.
Repair work is continuing today and signs have been put up advising people not to swim or collect shellfish until further notice.
Council spokesman Tim Harty said about 10,000 litres of untreated sewage escaped into the harbour.
He said repair work was continuing and although no more sewage was getting into the harbour, swimmers and shellfish gatherers were urged to keep out of the water as a precautionary measure.
This was bound to disappoint some holidaymakers, he said it could not be helped.
Mr Harty said the council would investigate why the sewer collapsed.
In 2014, the council was fined $56,000 for spilling nearly 5 million litres of sewage into the Raglan's Whaingaroa Harbour.
