Who are you wanting to target? People already in NZ looking for a new place to live or people from the UK looking to sort accommodation before they arrive here? And are you talking long term or holiday accommodation?Either way, TradeMe listings consistently show relatively high in search results (usually first page) because of the way their [blah blah blah, insert techno speak in here, something to do with algorithms? haha] are set up
I'm hoping to advertise my Wellington home as a temporary / short term rental to people from the UK are are relocating here. It will be available for four months. Not many people come to Wellington on holidays in mid-Winter so this is probably my only hope.
You should get in touch with Weta Digital. They often have people over on short contracts and used to have a small team whose job it was to help contractors find temp accommodation.....that was in 2010ish, but think they'll probably still be there.
