Anyone know if anything has changed since this 3 year old article?

http://www.consumer.org.nz/news/view/online-auctions-law-change-needed

I've noticed a few people on trademe selling new goods are refusing to fix/replace/refund items under the CGA if they break within a reasonable time as they where sold with "place bid" rather than "buy now"

Does the consumer have any protection with these people?

Thanks
