The ZB host pranked Ardern with face masks with his own face printed on the front.
The face masks featured four in total the "big one", "full body Mike", "multiple heads Mike", and "really multiple heads Mike".
"Next time you are on a plane you must promise me to put one on, selfie it and get it out to the world out on social media," Hosking asked Ardern.
She told Hosking, she thought he had gifted her a 'g-string'.
"When I first opened it, I briefly worried it was a g-string," Ardern laughed.
Hosking kept the 2020 theme going with his gift, while Ardern opted for a more electoral present.

She gave Hosking a Labour billboard featuring the ZB host alongside herself, a present she says Hosking will grow to love as the years roll on.
"Her gift to me is quite clever, and I'm going to treat it appropriately and put it in the right place. It's quite cool," Hosking said on air.
"Do you want me on board? Have you seen my magnetism as a vote-getter?" Hosking joked.
"Over time I will indeed learn to love it. I'll put it straight to the pool room."

Hosking also gave Ardern's daughter Neve a Micky Mouse soft toy with Neve's name stamped on Micky's foot, wowing Ardern as she unwrapped the gift.
"The Neve gift is sensational. The Ardern gift, God bless her for being a good sport. It could have gone either way."
