Relations between Australia and New Zealand, also sometimes referred to as Trans-Tasman relations due to the countries being on opposite sides of the Tasman Sea, are extremely close with both sharing British colonial heritage and being part of the Anglosphere. In this book, the authors gather and present current research in the study of the economics, environmental, and health care issues in both New Zealand and Australia. Topics included in this compilation include pharmaceutical contaminants in the New Zealand environment, environmental sustainability in Australia, the electricity distribution industry in New Zealand, specialist medical care issues in New Zealand, fisheries management agencies in Australia, climate change and child health in Australia, and coal-bed natural gas development and environmental implications in both Australia and New Zealand.
