National will support the Government's Paid Parental Leave (PPL) Bill, due to be introduced under urgency on Wednesday night.

The Bill will increase the number of weeks of PPL to 22 weeks by July 2018 and then to 26 weeks by July 2020.

Labour indicated the Bill would be introduced under urgency because it already passed through select committee when it was fronted by Labour's Sue Moroney.

It had enough support to pass, but National used a financial veto in June 2016 to prevent it progressing into law.

Now National's Simon Bridges has confirmed it will support the bill in a vote tonight.

"We'll be supporting that. Albeit, we don't think it should be under urgency.

"This is about being an effective Opposition while holding the Government to account."

Introducing the bill is part of Labour's 100-day plan.
