Oblivian: Big ol golfball on the port hills covers most of the south island

I had always thought that the main Radar for this was the one on the airfield.
Thought the golfball was the Metservice Radar

Me too. Till I looked into it more and found it was a field trip visit for trainee ATC :)

Wiki:

The prominent radar dome on top of Cass Peak is part of a nationwide system of air traffic management and is operated by Airways New Zealand. The nationwide system was built in the late 1980s and became operational in 1991.[16] Of the six secondary radar stations supplying the two air traffic control centres in Auckland and Christchurch with aircraft position data, Cass Peak is the southernmost in New Zealand.[17]

Rotating one on the ground is the older SSR

The one on the ground at CH Airport is a PSR, not an SSR.

It's not as clear cut as that...

There are two kinds of Radar, primary radar (the dish that wizzes around and pings moving targets basically), secondary radar where aircraft has a transponder and transmits its details back to base. Primary radar coverage isn't great - but we do have a reasonably good secondary radar system that covers a large portion of New Zealand and (oceanic) the Pacific.

The Radar Centre is solely based in Christchurch.

gzt: 'Internal network failure' aside, ATC obviously did well today recovering.

Btw how long has ATC in NZ had a national radar?

From how I believe it works is Airways base is in christchurch aviational tech park - Sir William Pickering drv. From there most the radar for the country is run out of. The towers at each field control ground/approach etc But when you are calling auckland radar, you are talking to one of the guys in a room down here. Able to hand off to those beside him/her

ubergeeknz: Who the hell designs a critical system like this to be centralised in a single location?

Have you forgotten about Telecoms launch of their XT network? They tried to be cheap and didn't purchase a redundant unit.
