Reina. Welcome to the forum.
It's such a pity you feel you have to go home after enjoying NZ for a year. Missing family and a network of friends is one of the major issues that migrants have to face and many don't realise just how much until they are thousands of miles away or until something major happens in their lives that they want to share.
As for selling your items, many thousands of people use TradeMe and usually get a result unless the stuff is considered to be overpriced. It depends how badly you need to sell it all as to whether you want to consider reducing the price. TradeMe is one site where people go to look for a bargain and hitting the right price has a knack to it. It's difficult trying to sell almost new things because you want the best price, but people seem to want to pay lower prices for used things otherwise they feel they could almost go out and buy them new anyway.
I would have thought NZers would be particularly interested in used cars because not too many of them can afford to buy new. I've heard it said that you can sell anything on that site, so it's a bit of a concern that you haven't managed to sell the items or the car.
I'm sorry I'm not much help and hope that you can find someone who will take the items off you for a decent price. This forum doesn't really deal with buying and selling or we would be inundated, particularly with opportunist trade adverts and all the immigration posts would be lost underneath them all

Good luck with your life back in the US
