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.

The diagram below shows the impact of the sinkhole on the Ōrākei main sewer. Watercare crews are working around the clock using hydro-excavation (jetting water) and a vacuum sucker truck to remove debris from the blockage inside the sewer. By midday Friday 29 September, they had completed excavation around the top of the sinkhole to make it safe. They will be spraying concrete like product on the slope to prevent more material falling in.

09:20 Climate change and its impact on our deadliest natural hazard

 Landslides are our country's deadliest and most costly natural hazard. Landslides triggered by the cyclone ultimately killed two volunteer firefighters Muriwai, condemned hundreds of homes, and left thousands of scars on the landscape. Months of painstaking work has since revealed the scale of the cyclone's devastation, with scientists mapping more than 140,000 slips. According to researchers at University Canterbury landslides have caused more deaths in New Zealand than any other natural hazard and lead to $300 million in insurance claims each year. Dr Timothy Stahl, School of Earth and Environment Senior Lecturer at University Canterbury, says climate change and natural hazards interact in a way that exacerbates the risk of damage to lives and property. He leads one of 10 university research teams awarded a combined $4.5 million in funding to better understand this relationship. 

09:45 Australia: Mideast fallout, referendum nears, the President and the paper baron

Australia correspondent Karen Middleton joins Kathryn to talk about how events in the Middle East are spilling onto the streets in Australia, with pro-Palestinian and pro-Israeli supporters clashing at the Sydney Opera House. It's just three days until the country's referendum on an Indigenous Voice to Parliament, what are the polls suggesting will happen? Australian paper and packaging mogul Anthony Pratt has been drawn into the latest travails of former US president Donald Trump with revelations that Trump revealed nuclear submarine secrets to the Australian businessman shortly after his defeat in 2020. And there's much soul-searching after the Wallabies' disaster at the World Cup.

10:05 The life of pioneering conservationist Richard Henry

A trip into Dusky Sound in 1974 led to Victoria Jaenecke's lifelong connection with Richard Henry. Appointed in 1894 as caretaker of Dusky Sound's Resolution Island, Henry spent 14 years  - much of it by himself - in the remote landscape where he fiercely defended kākāpō and kiwi against a tide of mustelids sweeping the mainland. Jaenecke's parents John and Susanne Hill used Richard Henry's notes and letters to navigate their way through the sounds in the 70s - with a young Victoria in tow - and later published a biography on his life in 1987. Following the death of her mother in 2014, Jaenecke and her father last year published Letters of a Naturalist: The Field Accounts of Richard Henry of Resolution Island

Letters of a Naturalist by Victoria Jaenecke and her parents Susanne and John Hill.
