I also contacted tm and told them they needed to check the auctions like Alan, and again they did nothing.
While I like colourful and beautiful fish, until the risks of GM are fully established, which they will never be, I will never feel comfortable with GM anything being in the country for sale.
I have in the last couple of days contacted the MAF line about fish being sold in Auckland as 'yellow glo fish', they have not returned the call so at least I consider I have been more proactive this time than with the above.
