Health Minister Tony Ryall has expressed his concern about the high rate of tattoo inks used in New Zealand which contain unsafe levels of toxic metals.
Mr Ryall was challenged in the House today about safety measures for tattoo parlours and the materials they used.
New Zealand First health spokeswoman Barbara Stewart asked whether he was concerned about the level of "heavy metal" in tattoo inks.
She believed young New Zealanders were increasingly getting back-alley tattoos from unlicensed operators and were exposing themselves to infection and scarring.
Mr Ryall said the Government had introduced new standards in 2011 through the Environmental Protection Agency which put controls on inks and set voluntary guidelines for managing and storing tattoo materials.
