Overlapping parental leave is the right idea – we just need more fathers to take it

New Zealand's National Party is proposing to extend paid parental leave from 26 to 30 weeks, but the more significant change is allowing both parents to take paid leave together. Currently, only one parent can receive paid leave at a time, forcing couples to use unpaid leave or annual leave if they want to be home together during early weeks. As the Conversation reports, allowing simultaneous paid leave strengthens parent-infant bonding and improves parental mental health—but the deeper benefit lies in how it shapes caregiving patterns. When both parents are home early on, they're more likely to establish shared caregiving routines, which means mothers are less likely to shoulder the bulk of unpaid domestic work later, reducing career penalties for women. The challenge is that fathers often hesitate to take leave, worried about career consequences. International evidence suggests the solution may be dedicated, non-transferable leave—like Sweden's model—where each parent is guaranteed leave they can't transfer, encouraging fathers to use it and normalizing caregiving as shared responsibility.
