Following Sunday's sewage leak that saw 15,000 cubic metres discharged into the Nelson Haven, the city council has confirmed another spill yesterday afternoon.
A further break in the Atawhai Drive sewer main was discovered at 1.20pm near Miyazu Gardens and Whakatu Marae.
It is not known at this stage whether the cause of the two leaks are related. The cause of the leak will be determined once repairs are complete.
Miyazu Gardens remains open as normal and there is no danger to the public.
The swim ban remains in place after Sunday's first sewer main break, and the public is advised again not to swim or have water contact in the Haven area until further notice.
This includes collecting shellfish from the area, which is banned at all times.
Warning signs remain erected at the Haven and the ban will remain in force until the discharge is completely cleared.
The council will notify the public when the swim ban is removed.
The repair to Sunday's sewer main break was completed at 4.30am on Monday.
It was caused by a buildup of sulphuric acid in the pipe over a long period of time, causing the concrete to become eroded
As with the spill over the weekend, the Nelson Marlborough District Health Board Public Health Service, Ministry of Fisheries, Department of Conservation, pollution control officials and local iwi have been notified.
Testing by the NMDHB's Public Health Service will follow repair work on the second spill.
