Labour MP Sue Moroney has been forced to concede defeat over her paid parental leave bill and instead is asking National to support a severely watered down version.
The new version gives extra leave to parents of twins or triplets, premature babies or those born with a disability.
Ms Moroney's members' bill to lift paid parental leave to 26 weeks will go before Parliament again tomorrow but the election result means she no longer has the numbers to pass it.
Instead she introducing an amendment to replace the universal extension in the bill with a much narrower provision to extend paid parental leave to 22 weeks in June for parents of babies born prematurely, with a disability or in the case of multiple births. It would lift further to 26 weeks in 2017.
Ms Moroney said she sent her proposal to the all the other parties in Parliament yesterday but was yet to hear back. Her decision to water down her original bill so significantly were forced by "political reality" - after the election National now had the numbers to vote it down.
