New Zealand Energy Strategy to 2050: Powering Our Future New Zealand Energy Strategy to 2050 Powering Our Future Towards a sustainable low emissions energy system October 2007 Acknowledgement The development of this New Zealand Energy Strategy has involved the help of dozens of organisations, associations, interest groups and individuals. Many have submitted documents and offered comment, either informally or formally, on the ideas and options raised in this strategy. These contributions have been invaluable to developing New Zealand’s future energy path.

The quest for sustainability is a defi ning issue of the 21st century. It has taken on a new urgency because of the scale of the environmental challenge the world faces. Traditional patterns of development and fast growing populations have put a huge strain on our planet. This government has put sustainability high on its agenda. In doing so, it has issued a call to action to make New Zealand a truly sustainable nation. Becoming truly sustainable is not only the right thing to aspire to – it’s also the smart thing to do. In a world that cares about sustainability, positioning New Zealand as sustainable is critical to our common future. It is fundamental to New Zealand’s ability to achieve our economic transformation objectives to ensure our future prosperity and international competitiveness. Making New Zealand sustainable can also stimulate new kinds of business opportunities to transform our abundant natural resources into higher value products, while protecting the environment. Government leadership on lowering New Zealand’s environmental footprint is making signifi cant headway. The government has released a proposal for an emissions trading scheme that will, in time, cover all sectors and all greenhouse gases. Tackling climate change will require each and every one of us to do what we can, with all sectors playing their part. The New Zealand Energy Strategy sets the strategic direction for the energy sector to contribute to New Zealand’s future prosperity and sustainability. Set within a framework of competitive markets and effective regulation, the strategy will ensure the right conditions for capital investment in coming years and provide leadership on energy security and climate change issues. The New Zealand Energy Strategy specifi cally responds to the challenges of providing enough energy to meet the needs of a growing economy, maintaining security of supply and reducing greenhouse gas emissions. The New Zealand Energy Strategy, along with the New Zealand Energy Effi ciency and Conservation Strategy, will take sustainability to new levels, by introducing initiatives that champion renewable energy across power generation and transport, energy effi ciency at home and at work, and the development and deployment of sustainable energy technologies. 5 New Zealand Energy Strategy | 2007 Part 1 Introduction The government has set a target for 90 per cent of electricity to be generated from renewable sources by 2025.

About this Document Solid Energy became a member of the Business and Biodiversity Offsets Programme (BBOP) and offered the Strongman Mine II as a pilot project in 2007. In 2009, Solid Energy together with BBOP published a case study on the biodiversity management and offset work undertaken at Strongman up to that point (available at http://www.forest-trends.org/documents/fi les/doc_3124.pdf). The present document serves as an update on the mine’s progress since then and following a second-party evaluation (pre-audit) against the BBOP Standard on Biodiversity Offsets (BBOP, 2012). For more detail and a history of the company’s work in applying the mitigation hierarchy and biodiversity offsetting, it is useful also to refer back to the 2009 case study.

  • Schedule of Responsibilities Delegated to Associate Ministers and Parliamentary Under-Secretaries
    Schedule of Responsibilities Delegated to Associate Ministers and Parliamentary Under-Secretaries 14 June 2018 276641v1 This paper is presented to the House, in accordance with the suggestion of the Standing Orders Committee in its Report on the Review of Standing Orders [I. 18A, December 1995]. At page 76 of its report, the Standing Orders Committee recorded its support for oral questions to be asked directly of Associate Ministers who have been formally delegated defined responsibilities by Ministers having primary responsibility for particular portfolios. The Standing Orders Committee proposed that the Leader of the House should table in the House a schedule of such delegations at least annually. The attached schedule has been prepared in the Cabinet Office for this purpose. The schedule also includes responsibilities allocated to Parliamentary Under-Secretaries. Under Standing Orders, Parliamentary Under-Secretaries may only be asked oral questions in the House in the same way that any MP who is not a Minister can be questioned. However, they may answer questions on behalf of the principal Minister in the same way that Associate Ministers can answer. The delegations are also included in the Cabinet Office section of the Department of the Prime Minister and Cabinet website (http://www.dpmc.govt.nz/cabinet/ministers/delegated), which will be updated from time to time to reflect any substantive amendments to any of the delegated responsibilities. Hon Chris Hipkins Leader of the House June 2018 276641v1 2 Schedule of Responsibilities Delegated to Associate Ministers and Parliamentary Under-Secretaries as at 14 June 2018 Associate Ministers are appointed to provide portfolio Ministers with assistance in carrying out their portfolio responsibilities.

  • ANNUAL INTEGRATED REPORT 2017 F.18A
    Reliable. Sustainable. Valuable. ANNUAL INTEGRATED REPORT 2017 F.18a Welcome – Tēnā koe For more than 150 years rail has played a vital role as an enabler of economic growth in New Zealand, evolving and adapting to meet customer needs despite significant geographical challenges and changing trends in trade. In the 1800s engineers designed a rail network that could operate in New Zealand’s uncompromising landscape, implementing wooden infrastructure that ran across swamps, rugged mountains, dense forests and wide rivers, to connect otherwise isolated communities and industries to the market. Much has changed since KiwiRail’s humble beginnings in 1863. Wooden infrastructure has been replaced by more resilient materials and today we look to advanced technological solutions to ensure the safety of the network and our people. To this day KiwiRail’s rail network continues to connect businesses, communities, importers and exporters to the world. As history shows, rail is adept at changing its services to meet the evolving needs of industry. As port flows increase and commuter demands continue to grow, KiwiRail is developing dynamic and innovative solutions to meet New Zealand’s changing transport requirements. 2 | Reliable. Sustainable.

  • Asset Management Plan (AMP)
    Asset Management2013 Plan www.topenergy.co.nz INTRODUCTION Introduction It gives me great pleasure to present Top Energy’s 2013-2023 Network Asset Management Plan (AMP). The 2013 plan follows on from the 2012 plan, addressing the key issues of reliability, security of supply and capacity. In this plan, we detail our reliability improvement programme as well as a significant transmission and sub-transmission investment plan over the next decade. This AMP is the core asset management planning and operations document for Top Energy and details inspection, maintenance and capital replacement strategies, as well as the service level targets that we intend to deliver to our customers. The Commerce Commission requires that electricity distribution businesses (EDBs) publicly disclose an AMP each year that provides information on how the EDB intends to manage its network assets to meet the requirements of its consumers. In compiling this plan, emphasis has been given to ensuring compliance with the Commerce Commission’s Disclosure Requirements, whilst also providing detailed information about Top Energy’s asset management and planning processes. In 2009, we introduced a major reliability programme which has targeted the clearance of trees near lines, the installation of automated switches and re-closers in strategic locations, and the use of specialised equipment to reduce the impacts of lightning strikes. This programme resulted in a significant improvement in the performance of the network in the last two years. At the time of writing, customers in the Far North have experienced 254 SAIDI minutes without power (on average) since the beginning of April 2012; a 28% improvement on the performance for the same period last year.
