Also, the initial estimate of the recovery cost following Vanuatu's twin cyclone disaster is estimated at six billion vatu, or just under $US50 million. And after four years of disruption, Polyfest has kicked off, with live audiences, in Tamaki Makaurau.

The unprecedented rainfall that hit Auckland on January 27 was, for many, a shock introduction to the city's old streams and waterways. Before urbanisation Auckland was a complex system of streams, rivers and wetlands - and the January flooding brought some to the surface with a vengeance. With climate change likely to bring more severe rain events, is now the time to think seriously about building up rather than spreading out into more green space, and daylighting more of the city's streams? Matthew Bradbury is a landscape architect, an associate professor at Unitec and author of Water City: Practical Strategies for Climate Change.

A group of health professionals and educators is calling for New Zealand to follow Australia's lead and make vapes prescription only. According to a study by the anti smoking group ASH, over 250,000 New Zealanders vape daily. Another survey of 19 thousand secondary school students, by the Asthma and Respiratory Foundation, found that more than a quarter of them had vaped in the last week - nearly 20 per cent vaping daily or several times daily - and the majority with high nicotine doses. In Australia vapes are prescription only - for people trying to quit cigarettes. However experts there say the system has many loopholes and further regulation is urgently needed. Kathryn speaks with Curtin University Professor of Public Health Jonine Jancey, whose latest research looks at the slick marketing tactics and claims by online vape retailers; and University of Sydney School of Public Health associate professor Becky Freeman who leads the Generation Vape research project. The interview discusses this article in The Lancet.

Film and TV reviewer Tamar Munch joins Kathryn to look at unconventional love story Rain Dogs (Neon), Elements of Truth: Behind the Scenes of Jami-Lee Ross' 2020 Election Campaign (Spinoff) and which movies have made the list for this year's 'Best Picture' Oscar.

Technology correspondent Paul Matthews joins Kathryn to talk about how Artificial Intelligence software that detects breast cancer missed by doctors is being rolled out into production now, leaving some doctors wondering what the future of their field looks like. The tech is saving lives - will we still need radiographers? The latest InternetNZ Internet Insights Report found that close to all New Zealanders can access the Internet at home now, but there are still discrepencies. So who is missing out and why do some groups still have big concerns? Some of the predictions of doom and gloom seemed to come true for Twitter last week, for a couple of hours at least. Turns out, a single engineer accidentally took the whole platform down. Paul Matthews is Chief Executive of CIO Studio.

An American mathematician is using maths and computer science to end the decades-old political tactic of gerrymandering. It's a practice used by both Republicans and Democrats in the US to manipulate electoral boundaries to influence elections and stay in power. It's sparked lengthy court challenges in districts where election outcomes have been unfairly skewed. Professor Moon Duchin from Tufts University heads up a research group which aims to make the voting system fairer by using geometry to redraw district boundaries. The civil rights advocate regularly appears as an expert in high profile legal cases involving gerrymandering and last year featured in the Netflix documentary A Trip to Infinity. She's in New Zealand to deliver a lecture at Auckland University, and joins Kathryn to explain how data science can be used to ensure a fairer system and bring about democratic reform.

UK correspondent Dan Bloom joins Kathryn to talk about how Rishi Sunak is banking his election recovery on a pledge to "stop the boats", as the number of people arriving on dinghies across the Channel has exploded. A new law would prevent migrants arriving this way from ever claiming asylum or settling in the UK, but it's outraged human rights charities and could be incompatible with the European Convention on Human Rights. Meanwhile former health secretary Matt Hancock has been burned by the leak of 100,000 WhatsApp messages, released by the anti-lockdown journalist who was the ghost-writer of his memoir.
