Aircraft Noise Community Consultative Group - Glossary of Terms (Version As at 7 May 2020) Aircraft Noise Community Consultative Group - Glossary of Terms (version as at 7 May 2020) Prepared by Catherine Harland, Independent Chair ANCCG Introduction The glossary that follows has been prepared in response to a suggestion that arose at a previous Aircraft Noise Community Consultative Group (ANCCG) meeting. The Quarterly and Annual Noise reports presented to the ANCCG include glossaries but the scope is limited with the focus primarily on noise. The wider aviation, resource management and other terms that arise in ANCCG discussions are not covered. Non-industry members of the ANCCG are typically not technical experts in these areas. That results in "information asymmetry" i.e. industry members have more or better information/knowledge than the other party. As a consequence, the ability of non-industry members to effectively pursue the purpose and activities of the ANCCG can be constrained due to insufficient understanding. To overcome that asymmetry industry ANCCG members (Auckland Airport, Airways, BARNZ) and supporting organisations, that attend the meetings from time to time, put considerable effort into explaining terms and providing educational and briefing information. That is very much a credit to them and is appreciated. To further assist in overcoming the information divide, this glossary has been drafted on a voluntary basis drawing on my experience over the past year as a non-industry, lay member of the Aircraft Noise Community Consultative Group (ANCCG). However, it does have limitations, as set out in the disclaimer below. My hope is that over time the glossary can be refined and improved to better assist non-industry ANCCG members, while at the same time not offending the professional, technical expertise of industry members. Limitation Disclaimer The glossary that follows has been prepared by me with the aim of providing high level, overview explanations of terms and industry matters sufficient for non-experts i.e. lay people. It is focused on terms that arise in the Aircraft Noise Community Consultative Group (ANCCG) which is established under Designation 1100 of the Auckland Unitary Plan. That means terms are defined in a manner that is relevant for the Auckland environment, not necessarily for other parts of New Zealand or elsewhere. The glossary draws on and is adapted from documents and information provided to the ANCCG over the years and on numerous websites with free, publicly available information. It does not purport in any way to give full, detailed technical definitions. While in most cases it is likely to be very accurate and useful, for any number of editorial or other reasons, it might not be. There may be errors. Please use your good judgement when using this resource and do not rely on it in any way for legal or other such purposes.

  • Annual Report 2020
    Financial Report 2020 Financial Statements This annual report covers the performances of Auckland International Airport Limited (Auckland Airport) from 1 July 2019 to 30 June 2020. This volume contains our audited financial statements. Overview information and a summary of our performance against financial and non-financial targets for the 2020 financial year are obtained in a separate volume, which may be accessed at report.aucklandairport.co.nz. 1 Financial report 2020 Introduction Auckland Airport is pleased to present the financial results for the year to 30 June 2020. This was a year of contrasting halves with the first half dominated by the company embarking on a historic period of infrastructure-related transformation and the second Financial report impacted by the travel restrictions put in place to mitigate the effects of the COVID-19 outbreak. The eight-month period to February 2020 was a period of transformation for Auckland Airport, with key milestones reached in the airport infrastructure upgrade, including the commencement of four of our eight key anchor projects. Auckland Airport also focused on delivering meaningful customer improvements including launching new automated pre-security gates, the continued rollout of check-in kiosks and the completion of the international departures upgrade. International air connectivity continued to grow in the eight-month period to February 2020 with new or enhanced services launched to Vancouver and Seoul. Regrettably, domestic passenger volumes marginally fell during the first half reflecting increased yield management by airlines and the impact of Jetstar’s exit from regional services. Following the global outbreak of COVID-19 and the subsequent imposition of travel restrictions from February 2020, Auckland Airport took a number of decisive measures to withstand the challenging and unparalleled operating environment.

  • Case Study: New Zealand
    Case Study: New Zealand Background Because of its geographic location, its dependence on tourism, and the absence of a comprehensive rail network, New Zealand has developed a large international and national airports network over the years. Until 1966, almost all New Zealand important airports were developed by the State and remained under the central Government ownership and management. There are three main international airports. First, Auckland Airport is the busiest and the main international airport. It is the only airport serving the Auckland metropolitan area, which gathers a third of the country’s total population. Second, Wellington International Airport is also a major domestic hub serving mainly business and government. International flights at Wellington Airport are principally from/to Australia. Third, Christchurch International Airport is the major international airport in the South Island, where it acts as the main hub and attracts a significant share of New Zealand’s international tourist traffic. There are other international airports in New Zealand, such as Dunedin, Hamilton, Queenstown, and Palmerston North, which also get flights from other countries (mainly Australia). Other commercial airports serve domestic and regional traffic. Commercialization/privatization: Airports The commercialization of New Zealand’s airports started early. First, the 1961 Joint Airport Scheme established the principles that resulted in both central and local governments jointly owning and operating airport facilities. The objective of this policy was both to benefit from the expertise of local governments on regional economic needs and opportunities, and to make local government directly invest in airport infrastructure. In 1974, 24 airports throughout New Zealand were under a joint venture ownership.

Last year our economic contribution to the region was $2.3b, supporting 11,000 jobs. While these large economic figures get thrown around a lot, we are currently seeing the tangible impacts of a significant reduction in that economic contribution. We all have a role in ensuring New Zealand remains a safe place to live, work and visit. At Wellington Airport, we are doing everything we can to support safe travel and enable freight to continue flowing in and out of the country. Tourism is New Zealand’s biggest export earner, supporting 365,000 jobs. We are working hard with Government, the New Zealand Aviation Coalition and the Australia New Zealand Leaders Forum to help the industry recover. As one of the best short stay destinations in the country, the Wellington region will continue to play a significant role in both domestic and international tourism. Like the entire aviation industry, our passenger numbers and operations were severely impacted by Covid-19 at the tail end of the financial year.

  • D24. Aircraft Noise Overlay D24.1
    D24 Aircraft Noise Overlay D24. Aircraft Noise Overlay D24.1. Description The purpose of the Aircraft Noise Overlay is to manage the subdivision of land and location of activities sensitive to aircraft noise in areas of high cumulative noise around the region’s airports and airfields, so that the continued operation of the airports and airfields is not compromised and reverse sensitivity issues are addressed. The following airports/airfields are included in the overlay: • Auckland International Airport; • Ardmore Airport; • Kaipara Flats Airfield; • North Shore Airport; and • Whenuapai Airbase. D24.2. Objectives (1) Airports and airfields are protected from reverse sensitivity effects. (2) The adverse effects of aircraft noise on residential and other activities sensitive to aircraft noise are avoided, remedied or mitigated. D24.3. Policies (1) Avoid the establishment of new activities sensitive to aircraft noise (except tertiary education facilities) within the 65dB Ldn noise contour in the Aircraft Noise Overlay. (2) Avoid the establishment of new tertiary education facilities and additions or alterations to existing activities sensitive to aircraft noise (other than existing dwellings) within the 65dB Ldn noise contour in the Aircraft Noise Overlay unless all habitable rooms and all learning, amenity and recreation spaces on site are located inside buildings and achieve an internal noise environment of 40dB Ldn. (3) Avoid establishing residential and other activities sensitive to aircraft noise at: (a) airports/airfields except for
