National says it will not support a Green Party proposal to give domestic violence victims up to 10 days' paid leave from work, but the bill could still have the numbers to progress.
Labour and Act say they will back Green MP Jan Logie's private member's bill at its first hurdle.
The Maori Party is also likely to support it, though its MPs have some concerns about whether victims' privacy could be breached if they applied for leave because they had been abused.
New Zealand First and United Future are yet to confirm their position, but their support would mean the bill had the required 61 votes to pass its first step.
The bill was scheduled to come before Parliament on Wednesday but its first reading has now been delayed until March 8.
