Wairarapa midwife Clare Bardsley said parents were learning to reduce such risks.
"It's a Ministry [of Health] requirement that we discuss safe sleeping with all women," she said.
"Our three key messages are: baby to sleep on its back, baby to sleep in its own space, and no smoking before birth and during breastfeeding.
"I think [the messages] are getting through well. When I discuss those with women, they're not surprised to hear them."
Pepi pods were a great idea but were hard to come by, she said. "It would be great if we could send every woman in New Zealand home with one."
A pepi pod is a plastic box with a mattress, cover and bedding package, including a top sheet that wrapped the baby securely to keep them on their back while sleeping. They are designed for babies up to 6 months old.
Nationally, the number of Sids deaths fell from 57 in 2007 to 18 in 2012.
SIDS and Kids New Zealand chief executive Margaret Free likewise believed parents were becoming more aware of risk factors.
"We get about three or four calls a day, at least, from parents who want to know about what they can do to prevent Sids," she said.
"There's also been a real push of our safe sleeping programme. We give out pamphlets in hospitals, and we're about to release new pamphlets in motels for itinerant travellers."
Parents should also be aware of babies overheating in winter, she said.
"There have been a few deaths in the past caused by babies being overheated."
