Ms Kitson said this criminal market was an ongoing concern for small art galleries. "It had been quite a while for us, and you always have that feeling that your luck only stretches so far before the crooks decide that they'll visit you again."
Such distinctive artworks were unlikely to be re-sold in any legitimate market that requires proof of purchase, she said.
"Because our works are one-offs, you can't legally do anything with them. So it's only for the underworld of sorts. You would never actually get the proper value of anything you stole."
Despite having security camera footage of the theft, Ms Kitson doubted they will recover the stolen item.
"Sadly when things do go, they go high up the food chain and you don't often get them back. You may catch the crooks, but you don't often get the works back."
Auckland police were unable to comment on whether there is a connection between the two burglaries, or whether there is any link to drug dealers.
