As Cabinet starts to consider a vision for a post-lockdown future, and Australia prepares to trial vaccine passports with selected countries, questions are being asked about impacts on liberty and privacy for vaccine passport use within a country.  Prime Minister Scott Morrison says once 80% of adults have had two shots, people will be allowed to travel overseas again. Proof of vaccine records will be needed for outgoing and inbound travelers from the Pacific, the UK and the US, also Singapore, Japan and South Korea. Proof will take the form of a QR code linked to an actual passport.  Our Ministry of Health has confirmed vaccine passports will be available for Kiwis later this year.  Meanwhile the UK has rowed back on vaccine passports for use within England, for fear of limiting freedoms and creating a two-tier society. Lynn speaks with Dave Parry, professor of Engineering, Computer and Mathematical Sciences at the Auckland University of Technology, Dr Andrew Chen, a Research Fellow with Koi Tū: The Centre for Informed Futures at the University of Auckland and Justine Nolan - law professor and the director of the Australian Human Rights Institute at UNSW Sydney.

Researchers at the University of Canterbury say they are at a breakthrough point in a project to substitute fossil fuels with green hydrogen gas and carbon dioxide. They've been examining how wood waste can be broken down to create these two products, which could be used in plant nurseries to grow vegetables, also in fertiliser factories and chemical plants instead of fossil fuels. The current thinking is their system could produce climate-friendly hydrogen and carbon dioxide at scale in about a decade.  Lynn speaks with Associate Processor in Chemical and Process Engineering the University Of Canterbury Alex Yip, who is leading the team.

Kate Macdougall's memoir London's No. 1 Dog Walking Agency  is an entertaining perspective on a left-field profession and a coming of age story.  Armed with a degree in Art History, and eschewing a back office job at Sotheby's auction house, it tells of Kate's efforts to strike out on her own, starting up in business as a dog walker for busy Londoners whose pets otherwise faced long and boring days home alone. While receiving strict instructions about diet, mud and treasured balls, Kate got the measure of other peoples' lives, and, as she tells Lynn Freeman, her own.
