Auckland sinkhole: What's the fix and long-term damage?

It's being called Auckland's worst pollution event in nearly 50 years. It's two weeks since a massive sewer line collapsed in Auckland, leaving hundreds of litres of human waste pouring into the inner harbour every second. Kathryn is joined by Watercare's head of service delivery Sharon Danks to talk about the bypass solution that could be in place in a week - will be a complete fix to the sewage overflow? Also marine scientist Dr Andrew Jeffs from Auckland University on the long term damage being done to the environment and how long it'll take before water quality improves.
