1This week the Invercargill City Council set itself the target of becoming New Zealand's most child friendly city. The 55 suggestions the council is considering to make that more than simply a slick marketing slogan include: hosting a national toy extravaganza; having more swings per capita than any other centre in New Zealand; opening a children's theatre; adopting child friendly transport policies; and offering families financial incentives to move to the city. This week on Ideas we discuss the concept of Child Friendly Cities with Invercargill Mayor Tim Shadbolt; UNICEF's Barbara Lambourn; and Otago University Associate Professor of Planning Claire Freeman. We also hear from a couple of children from Wellington's Te Ara Hou flats who have helped design and create a new playground.
