Apple has increased their price for Wireless router like AIrport Extreme, Time Capsule 2T and 3T significantly. Probably due to the USD and NZD exchange rate.
Noel Leeming is still selling these products at old price and they are having double Fly Buy points at the moment. I just got one Airport Extreme before all they increase their price.
Example:
