There's no time limit on the ability to claim your statutory consumer rights specified in the Act. I suspect it would be based on 'reasonableness', and that you would be entitled to a remedy, especially after just 90 days.
/edit in terms of "Acceptable Quality" (which I think is what we're talking about here), even in regards to second-hand goods, it would only take into account age, price and condition. So if they're selling 'like-new' items as pre-owned, but they're more or less off the shelf, then that would be factored into it.
Bottom line, it seems likely that it would apply. Use the Competition and Consumer Act though, not the TPA.
I used this guide by the ACL and I also looked up the Act itself, though it's a bloody impenetrable minefield at times.
