Cards containing blood spots from heel prick tests on newborn babies will be kept indefinitely with enhanced access protection, the Government has decided.
The blood spot cards, known as Guthrie cards, have been collected since the late 1960s as part of a screening programme.
The Ministry of Health had intended keeping them indefinitely but concerns about privacy issues were raised, and until now there had been no formal government position.
Health Minister Tony Ryall says the cards were an important part of the screening programme for babies and identified those with serious metabolic disorders.
Mr Ryall said there would be new protection around the cards including written consent for them to be used for research and the privacy commissioner was considering developing a code which would regulate the use of information.
The cards were used to identify victims of the Christchurch quake, and may be used to identify Pike River victims.
National Testing Centre director Dianne Webster told Radio New Zealand five of the cards were released for victim identification in Christchurch and the centre is in discussions with police about their use for Pike River.
