Officials are looking into the safety of some baby monitors following the deaths of infants overseas.
The Ministry of Business, Innovation and Employment says it is looking into whether recalls are required for monitors that use a sensor in the crib to detect movement. The sensors are attached to the monitors by a cord.
Two babies died of strangulation in the United States in 2004 and 2011 after they pulled the cable of an Angel Care monitor loose and it wrapped around their necks.
The owner of Child's Play, which distributes Angel Care monitors in New Zealand, says the device is completely safe if it is set up correctly.
However, David Austin says he is offering concerned parents free cord covers to secure the cable out of their child's reach.
Mr Austin and the ministry are urging parents to make sure that the device is set up properly.
