Information by Abdrew Joll
The site is the main FM transmission site for Auckland now,
taking over from Waitarahua (which remains the main TV site). You can lookup spectrum licenses in NZ by site, owner etc at

These
photographs of the stunning AUCKLAND SKYTOWER in New Zealand are by
Professor Anthony C Davies who has also kindly provided us with some
background information:
"The Auckland Skytower is mainly an entertainment
centre, restaurants, casino, bungee-jumping site, etc. (called Skycity)
but the upper part does have a substantial amount of TV, FM radio and
other antennas. I tried to get more data while I was there, but
was passed from one helpful person to another, none of whom were able
to give any help at all - and I did not have time to go up the tower to
see anything from closer to.
The height is 328 m and the Aukland Skytower is the tallest structure
in the Southern
hemisphere. Among other things, transmits TV3 (182.25 MHz) and
TV4 (45.25 MHz), both horizontally polarised, and transmits FM radio
(probably includes 100.6 and 105.4, vertically polarised.
The publicity says it is '....the largest FM combiner in the world (the
most stations transmitted on one aerial).......' and has 38 microwave
links too. - but this information is intended for the
general public, so does not really explain much. The TV
broadcast antenna side is installed by Lincrad Aerials NZ Ltd,
Christchurch. They seem to be responsible for all the broadcast
antenna systems in New Zealand, as well as marketing domestic receiver
antennas for TV, etc. Perhaps technical data could be obtained
from them.
TV in New Zealand uses bands one and three as well as UHF, and some of
the composite domestic receiving antennas are very intricate
structures.
The transmitted material seems to be almost continuously atrocious but
that is another matter (advertising seems in total control, the
transmissions appear as a continuous sequence of long adverts, with
brief moments of actual programme inserted from time to time!
However, since we spent as little time as possible looking at TV,
and as much as possible looking at the magnificent NZ scenery, maybe
this is not a fair judgement (but perhaps what we can look forward to
from a privatised future 'BBC'!). "
