Meteorological products and services for civil aviation in New Zealand can only be provided by organisations certificated to do so by the CAA. Under Civil Aviation Rule Part 174 - Meteorological Service Organisations, the Meteorological Service of New Zealand (MetService) and the Airways Corporation of New Zealand (Airways) are certificated to supply various categories of services. The majority of such services are currently provided by MetService.
There is no formal requirement from government for MetService to provide meteorological services to domestic civil aviation. The CAA is the International Civil Aviation Organisation (ICAO) Meteorological Authority in New Zealand, and, as such, gives exclusive license to MetService to carry out the operational requirements prescribed in ICAO Annex 3, Meteorological Service for International Air Navigation. This includes the provision of OPMET (TAFs, METARs, and SPECIs for Auckland, Wellington, and Christchurch aerodromes, and SIGMETs for the New Zealand and Auckland Oceanic FIRs).
This area of the CAA’s web site is intended to provide an up to date overview on access to, use of, and interpretation of aviation meteorological information by all sectors of the New Zealand aviation community.
|From 26 June 2018, the GRAFOR (Graphical Aviation Forecast), along with the recently released Graphical NZ SIGWX (GNZSIGWX) chart, will replace the text ARFOR. These changes will swap pages of text with graphics and will provide the same level of information as the current ARFOR, displayed spatially on a map. Wind information will be available in the same format as is currently used, and will be called Aviation Area Winds (AAW). Details are in the pages below.|

Meteorology Symposium 2
The CAA is holding the second of its Meteorology Forums on 3 October 2018. This event is intended to get all of the interested parties in one place to look at the overall MET situation, the issues and the developments both local and international. The formal objective is to better support the dynamism of aviation in the region, through a regular aviation MET industry meeting where the users, providers, and regulators can come together to co-ordinate and collaborate efforts with the objective of ensuring what is done, and what is developed, is optimal, responsive, and sustainable.
If you would like to participate, see the draft agenda below and let Peter Lechner know at firstname.lastname@example.org.
