Jacinda Ardern shared a photo of baby Neve, albeit mostly out of view, on Instagram, with her favourite toy.
Neve's hand is holding an old soft toy which Ardern says in the caption used to be hers.
"Amongst a few other options, Neve has settled on this pretty worn and misshapen bear.... the same one I had as a baby," the Prime Minister wrote.
"The benefits of having a Nana who hoards."
Neve's brown bear toy was a hit on Instagram, with nearly 25,000 likes in just a couple of hours.
