When I came to New Zealand in 2007, I missed out on renting the house that I wanted just because it was unfurnished and my stuff had not yet arrived - so I lost the house and had to remain longer in the small furnished duplex I had rented.
So, when I recently came across a franchise company called MrRental I thought I would bring it to the attention of everyone here. They rent everything from white ware to electronics and furniture - short or long term. You may also find that the extra cost in renting a furnished vs unfurnished place could offset the cost of renting the furniture etcetera.
I understand that MrRental have offices all over the country – see http://www.mrrental.co.nz/stores. The owner here in Whangarei, where I live, is Mark Bogle, if you want a personal contact.
I just thought that this may suit those of you whose furniture is still back home or on the ship.
Happy travels.
