The number of women seeking help for birth injuries remains low, two years on from changes to allow ACC to begin funding treatment.
Last year, there were just under 57,000 live births, but in the past two years just under 14,000 claims had been lodged.
Wellington pelvic health physiotherapist Liz Childs told Nine to Noon it was not obvious where to get help.
"People are missing out," she said. "A lot of people aren't aware of the risks, or they don't know where they can get help, or they don't know how to access it."
"Just because you don't have symptoms doesn't mean that you're not going to later."
She said there were still financial barriers, as the treatment was not fully funded by ACC, and private physios had to charge a surcharge.
"There's a lot of people who can't afford to come," she said. Often women weren't working after having a baby, and they would be thinking about their baby, not themselves.
Women who had given birth vaginally were also sometimes unaware of the recovery needed before they returned to exercise or work, which lead to injuries further down the line.
ACC told RNZ it had paid out $6.8 million in the past two years - and Childs said this was well below what she would expect.
