Interest grows in auction of single-use plastic bag on Trade Me

One week on from the single-use plastic bag ban at many of our supermarkets, one canny punter has put a Pak'nSave plastic bag on Trade Me that's sitting at around $50.

Without plastic bags, shoppers are having to get inventive. They're seen clutching precariously balanced shopping to their chests; using a trolley to ferry goods to the car; borrowing the supermarket basket; getting the kids to carry it; or, most sensibly, bringing their own recyclable plastic bags.

Most shoppers Newshub spoke to welcomed the bag ban.

"It's great, we really support it.  We have our own bags - not today though!" shopper Carolyn Roberts-Thompson said.

Another said it's going well, with people quite happy to follow the rules.

But shopper Anne Spencer pointed out, "There's a lot of plastic around meat, around vegetables, and I think they should have done that first."

Single-use plastic bags are now apparently becoming a valuable commodity, with 72,000 views of a single-use Pak'nSave bag up for auction on Trade Me.

Seller Nairn Wilson listed it as a bit of a joke, to see if it got any attention, and it has.  And, he's had some interesting questions from potential buyers.

"Whether or not there's a 'buy now' price; about the consumer warranty; the condition of the bag; and questioning the authenticity of it," he said.

Trade Me's Millie Silvester said they like it because "it's topical and they're having a bit of fun with something that all of New Zealand is talking about".

It's not the first time plastic bags have been listed. Last year someone sold 200 single-use bags ahead of the ban, calling it a "Bag-ageddon - Emergency Survival Kit".

So, with a plastic bag ban, what should you line your rubbish bin with?

There are tutorials on how to make a liner out of a newspaper, but you'd have to buy newspapers regularly for that.

Now, some says they will buy plastic bags for the job.

"I will have to now, because I used to re-use them when we came shopping," Anne Spencer said.

"We buy a bin liner, yes we do," said Carolyn Roberts-Thompson.

The mandatory ban of single-use shopping bags takes effect in July.

The Ministry for the Environment said bin liners aren't included in that.
