Land Rover Hire in New Zealand

[The Curn]

I'm travelling to New Zealand in February 09 for three weeks and would like to hire a Land Rover. Pick up at Auckland Airport.

Not fussy;

Freelander 2 (diesel or petrol)
Disco 2 or 3 (preferably a petrol)
Range Rover L322 or P38 or even a Classic (must be petrol)

I have scoured Google to find hire companies but have so far drawn a blank.

New Zealand 4WD Hire have had all their Land Rovers block booked by a bloody travel agent and only have a Kia left. They don't know of anyone else.

Does anyone else know of anywhere else or have any ideas??

And, yes, it does have to be an LR because I'm paying and I like them!
