North Shore Toyota are the TRD suppliers into New Zealand, and also I believe Australia.
Being that they're linked into the Toyota/TRD systems, they're able to give the advice that you may have overlooked.
Other than TRD parts, (the good TRD JP stuff, not the TRD USA rubbish I see all the time) I have found them very competitive on many other brands. Over the last year, I've purchased from them:
TRD
Toms
Toda
CP
Eagle
Whiteline
Motul
Cusco
HKS
as well as genuine Toyota parts.
I wanted to get a rear spoiler from an RC86, my local dealer wanted $1300 (and said he was doing me a deal) NST said they would do for under $400.
Prices are always sharp. The odd time you might find another supplier (who might be sneaking it into the country to avoid import duty) beats them by a few percent, but thats not all the time, and I find myself ordering from NST anyway, as they're a 'bricks and motar' business, with great service.
The majority of us in the NZ owners club get the majority of our parts through NST, and I believe a lot of the Aus guys do as well.
The main guy there is Nick. His email is

Highly recommended for anyone on this side of the pond.
