Trademe is getting rid of Safetrader which was very useful in the past for me.
They claim that their new 'Raise a Dispute' negates the need of Safetrader but unless you use their credit system as a seller or buyer you have basically no protection see here:
Recently I received goods described as new, arrived damaged/broken/unusable and after politely letting seller know (who didnt give a toss) had the time wasting experience of using TradeMe Disputes which ended by them sending me this result:
We've found the best way to resolve disputes is through good communication, so we've contacted this trader with your concerns and encouraged them to come to an agreement with you. We'll also be keeping a close eye on the membership from now on. At this stage you may like to pursue this matter through other forums.
