He was confident the chance of a baby with a congenital hearing loss being missed was low.
Babies who had either been admitted to the Special Care Baby Unit, born prematurely or who had a known risk of congenital hearing loss were given a different screen and were, therefore, not at risk and not part of this recall, Dr Moore said.
Parents would be sent out letters, on a staggered basis, during the next 12 weeks offering appointments to have their child's hearing rescreened. Parents were urged to take up this offer, he said.
Hawke's Bay had identified a large number of children to be rescreened.
It was the first District Health Board to begin the screening programme, and had three screeners working who screened the 120 or so babies born each month.
Parents who were concerned could see their GP or WellChild Tamariki Ora provider or could call 0800 643 745 for more information.
