Jacinda Ardern has skyrocketed in popularity over the past few years, and there's no doubt she 's-mash-ed' the election.

Her big wide smile is 'ap-peeling', inspirational messages 'spud-tacular' - and according to election results, 49 percent of Kiwis 'rooted' for her.

The Prime Minister recently posted on her Instagram one of the most bizarre gifts she's been given… a potato.

"I get sent some amazing things. I get sent some interesting things. And sometimes, I get sent a potato," she posted on Tuesday.

"Thank you to whoever sent it to me, the accompanying puns were spectacular."

"Congratulations on your spud-tacular victory," a fan wrote on the potato.

"You smashed it again."

The humble potato has played an important role this election.

Days before the October election, National leader Judith Collins defended her comments about how obesity is a "weakness" by referencing her fondness for potatoes.

Speaking to Ryan Bridge's Magic Talk show, Collins was asked whether she considered herself obese.

"Well I think I'm overweight, I'm definitely overweight," she replied.

But Collins said we can all make personal choices around food - including herself.

"I find it very difficult to resist anything with potato in it so the best thing for me to do is to not buy potatoes."
