NZ drives me nuts, on average 44 days per year are disrupted at NZCH with Fog which costs millions for the airlines and passengers. Back in 2017 there was this article in which the owners of NZCH are quoted as saying a full CATIII system would cost $14 million to install. Well that seems cheap to me, they must spend that at the drop of a hat when it means they can add car parks or shops or hotels? Spend some money where it is important for god sake.
