According to https://www.stuff.co.nz/business/113447617/fog-delays-at-nz-airports-could-be-blown-away-by-transtasman-technology-project (https://www.stuff.co.nz/business/113447617/fog-delays-at-nz-airports-could-be-blown-away-by-transtasman-technology-project) (15 June), "The [NZ] Government intends to piggy-back on an initiative by Australia, which last year earmarked A$225 million (NZ$238m) to buy and operate a Satellite-Based Augmentation System (SBAS) that will improve the accuracy of GPS location data from about 4 metres to just 10cm."

Is this just WAAS (the US Wide Area Augmentation System), or are the Aussies going to invent something uniquely Australian?
If it is WAAS, why do we have to work with the Aussies, and why is it going to take four years?
The Japanese already have two WAAS-compatible satellites in geostationary orbit (they call the system MSAS / Multi-functional Satellite Augmentation System), and presumably NZ could latch onto that by installing some ground stations and paying the Japanese civil aviation authorities a licensing fee to access their satellites.
All modern (or even modern-ish) aircraft should already be fitted with a WAAS-compatible satnav system, as it is widespread in high-volume parts of the world - as well as the original US WAAS and the Japanese MSAS, there's EGNOS (the European Geostationary Navigation Overlay Service).
