Clarke Gayford has shared a picture of a special present sent to his daughter Neve Te Aroha Gayford Ardern on her first birthday by a royal friend.
Prince William has sent Prime Minister Jacinda Ardern and Gayford a traditional Kiwi Buzzy Bee toy with an inscription on a silver plaque on its underside that reads: "Happy Birthday Neve. From Prince William."
Gayford posted a picture of the present on Twitter with the caption: "Torn between letting the 1st birthday girl continue to maul this amazing gift or putting it somewhere safe FOREVER.
"Happy Birthday Prince William, what a great shared birthday (I'm pretty sure you win with this)".
Gayford was referencing the fact Prince William shares Neve's birthday of June 21 in his post.
The gift has extra poignancy as the Prince was also gifted a Buzzy Bee on his first royal visit to New Zealand as a nine-month-old in 1983.
Footage of the young Prince playing with the toy on the lawn of Government House in Auckland was broadcast around the world.
Meanwhile Prime Minister Jacinda Ardern has also taken to social media tonight, thanking all the people who have supported her family over the past year since Neve's birth, and saying she's trying to bake a cake for her daughter's birthday.
"Doing what so many parents have done before me. Waited till baby was in bed before trying to magic up a passable cake for the big first birthday. Wish me luck," Ms Ardern wrote in Instagram.
Her post was accompanied by a photo of a Women's Weekly magazine cover featuring 'Kids' party cakes'.
"PS to the many, many people who have wished our family well, sent knitted goods and passed on a piece of wisdom about parenthood over the past year - thank you," Ms Ardern wrote in her post.
"It truly takes a village (and someone in said village may get a call if I don't sort this cake!)" she concluded.
