A Gisborne medical centre has been forced to close after torrential rain forced raw sewage back up its pipes into toilets and sinks.
On Monday, The Doctors sent a memo to all patients saying it could only do phone consults this week due to health and safety reasons related to the issue.
A small number of patients have been seen in person at a cabin outside the Desmond Road clinic, but the centre said the sewage had caused major disruption.
"I cannot describe the smell, it's horrendous," centre manager Paula Neshausen said.
It is not the first time the clinic has been plagued by the problem, with the same issue unfolding during cyclones Hale and Gabrielle.
Neshausen said she had contacted Gisborne District Council about it multiple times, and again last Thursday, but a long-term solution was yet to be found.
"We ring and put through the request, and we don't hear anything back. We don't get any updates, we get nothing.
"It's really frustrating... it really feels like the council doesn't care about the health of our community."
On top of the health concerns, rearranging appointments put extra stress on both patients and staff, Neshausen said.
Fulton Hogan contractors sucked excess water out of the drains on Tuesday, meaning things were beginning to return to normal, but there were still concerns about what the next big rain could bring.
In response to questions from Local Democracy Reporting, council community lifelines director Dave Wilson said the council had not received reports of any issues at The Doctors until Monday morning, at which point its contractor went out immediately.
The issue was due to excess rain entering the sewer system and a clean-up was the only option until levels receded, he said.
"Wastewater is running at around 450 percent of normal flows which brings a whole new set of challenges, including sewage not being able to escape.
"We have been working to try to manage the wastewater network since Thursday last week."
Wilson said at its peak, the system was experiencing 600 percent of normal flows due to the amount of water flowing through.
"We have had a number of issues with wastewater backing up on to private properties across the city network, which we apologise for."
Residents with wastewater issues were encouraged to contact the council, which could send teams out to clean and disinfect properties, Wilson said.
