A fertility clinic believes National's promise to fund more IVF treatment will speed up access for eligible couples.
The party is committing to fund a third free fertility treatment cycle - that's one extra cycle for eligible parents.
That will bring the country up with other developed nations like the UK and Australia.
Fertility Associates CEO Alex Price says the impact for parents will be "life-changing".
"If you do more IVF cycles, then you actually get more babies," Mr Price said.
"It's certainly an approach to be encouraged."
Mr Price says there are roughly around 1400 to 1500 cycles of IVF done every year that are publicly funded.
"We're probably going to see another perhaps 300-400 people undertake that third cycle of treatment (under the National initiative)."
"So while it might seem a relatively small number of people, it will make an enormous difference to those people, being able to access treatment."
