A new book tells the story of Aotearoa New Zealand through the maps that guided our first inhabitants and the explorers and settlers that followed. Singing the Trail digs back into the history of the maps, the map-makers, and those who were using them. From the oral maps made by early Polynesian and Maori settlers, in songs, karakia and stories, to Abel Tasman's early efforts, to James Cook's more detailed maps that helped him circumnavigate Aotearoa. Author John McCrystal has written, co-written or ghost-written over 50 non-fiction titles on a diverse range of subjects, including biography, social history, travel, sport and economics.

Alice Cooper was originally the name of a band. Then singer and harmonica player Vincent Damon Furnier took the name for himself and went solo. In the Seventies he became a bona fide rock legend and carved out his own distinctive style: blending heavy metal stylings with the trappings of horror...think snakes, lashings of fake blood, leather trousers and heavy make up. And there was cocaine too: lots of cocaine. Shock Rock was born! And the act's been working for him ever since. Now a tee-totalling golfer, Alice Cooper returns to New Zealand on the "Ol' Black Eyes Is Back" tour in February 2020 for gigs in Auckland and Christchurch.

Becky Bateman is an astro-tourism operator involved in plans to turn Wairarapa into New Zealand's second dark sky reserve after the Aoraki Mackenzie Dark Sky Reserve, and alongside dark sky sanctuaries on Great Barrier and Stewart islands. She wants to bring more local and international visitors into the area to stare at the stars. The establishment of the South Island reserve in 2012 is credited with giving the local economy a major boost. And there are even ambitious plans to turn the whole of New Zealand into the world's first 'dark sky nation'. This topic was recently discussed at a national Starlight Conference with representatives from the US National Park Service and the International Dark-Sky Association, the international body responsible for deciding whether an area qualifies as a true dark sky area.

Dr John Peterson 'Pete' Myers is a US environmental scientist acknowledged as a pioneer of research looking at how plastics in food packaging and in the environment could be affecting health.

Trans-national arranged marriage has been in the news this week with debate over immigration policy and recent comments from New Zealand First MP Shane Jones. Many community leaders have defended the cultural practice but others believe it is time to scrutinise how these marriages can increase women's vulnerability to abuse. Farida Sultana is the founder of the New Zealand branch of Shakti which provides "culturally appropriate domestic violence intervention services to women of Asian, African and Middle Eastern origin". From a Muslim Bangladeshi background she had help from Shakti Women's Aid in Scotland to leave an emotionally abusive arranged marriage.

The Guardian's health editor Sarah Boseley's campaign to highlight the plight of child labourers working in the tobacco industry in Malawi has prompted human rights lawyers working for UK law firm Leigh Day to prepare a landmark class action highlighting the labour practices of British American Tobacco. Meanwhile, the US has suspended all tobacco imports from the African country over the child labour allegations. Other multinationals will be closely following the lawsuit to see how far it could impact on their own operations.

British neurosurgeon Professor Steven Gill is trying to halt, or even reverse, the development of the progressive neurological condition Parkinson's with an experimental drug: GDNF. Medical trials for the drug were the subject of the BBC Two documentary The Parkinson's Drug Trial: a Miracle Cure?

Artist Louise Henderson (1902-1994) worked alongside major New Zealand art figures including Rita Angus, John Weeks, Colin McCahon and Milan Mrkusich and developed a bold, colourful and distinctive abstract style. Despite her prominence there has been no comprehensive survey of her work until now.

Kim asked Julia Waite, one of the curators of a new exhibition celebrating Henderson's life and work, why it's taken so long to recognise her achievements.
