A sewage spill has closed multiple roads in Wellington as wastewater spews into the harbor. 

On Friday a tunnel in part of the wastewater network in Wellington's CBD collapsed, sending wastewater into the sea. 

Wellington Water is scrambling to control the damage. Crews worked throughout the night to divert the sewage, but it says more work is required.

Two major CBD roads have been closed and motorists have been told to expect "significant delays".

Willis St is closed between Vivian St and Manners St, and Ghuznee St is closed between the Terrace and Victoria St.

A rāhui was placed on swimming in the harbor. Wellington Water says no one should enter the water or fish from it. 

"At this stage it is unknown how long this will last for, or the volumes of wastewater that will be discharged," said Wellington Water in a statement on Friday.

"We are working to try to divert the flows through other parts of the network."
