Take a look at www.trademe.co.nz and go to the flat hunt section. You have to sign up, but it is free
There you should be able to find something that suits you. Seeing as you are looking to work at either CHC
, I suggesr that you look at places in the area of 'Mangere' or 'Manukau' or 'Papatoetoe' in AKL
, and 'Harewood' in CHC
. These suburbs are close to the airports in their respective citys.
, the surrounding areas to the airport tend to have cheaper accomadation than in the central city.
Another place to look at in AKL
is the area called 'Botany Downs', 'Pakuranga' or Howick'. This is a very safe area and it has loads of shops etc... It is pretty much it's own city. Howick, Botany, and Pakuranga also is the only suburbs to have a direct public bus service to the airport.
If you have any more quieries, just email me and I'd be gald to help you out.
