Within: Projects and resource management (including environment)

DLA Piper New Zealand's resource management and environment practice acts primarily for government and local government clients, though it also handles significant work for private sector clients. The firm is a key adviser to Auckland Council on local and national planning documents and policy, development projects, consenting and enforcement matters, as well matters in the District Court, Environment Court, High Court and Court of Appeal. Stephen Quinn in Wellington leads the practice. He recently advised the Department of Corrections on the environmental approvals required for the expansion of Waikeria Prison in Waikato. Senior associate Emma Manohar also played a key role in that work. Kerry Anderson jointly leads the RMA practice in Wellington with Quinn and frequently advises Auckland Council. In a recent matter, she acted for Wellington City Council and Greater Wellington Regional Council in a major roading project, handling the implementation of consents for the Transmission Gully. Diana Hartley in Auckland is highly recommended, particularly for urban growth and intensification matters, rural issues and infrastructure projects. Senior associate Anne Buchanan also has significant expertise in resource management and local government law.

  • Sentencing guidelines for corporate manslaughter

    In February 2010 the Sentencing Guidelines Council (the SGC) issued definitive guidelines to courts on imposing appropriate sentences for corporate manslaughter and health and safety offences causing death. The SGC states that fines imposed on companies found guilty of corporate manslaughter should not fall below £500,000, while fines in respect of health and safety offences that are a significant cause of death should be at least £100,000. Crucially, the SGC declined to provide for a fixed link between the imposed fine and the turnover or profitability of the offending company.
