Jared Mullen and Ryan Tunstall, of Oregon and Australia, respectively, said that their daughter Isabella and George were "chums" after having "a little play together."

The couple were among 10 chosen by Plunket, a parent support organization, to represent the growing number of New Zealand's same-sex couples who use Plunket’s services.

“The parents are a spread of all the communities in New Zealand, including Maoris, Samoans, people of Chinese descent and gay couples," said Plunket president Tristine Clark. "This is a very multi-cultural country and we wanted the Duke and Duchess to meet people from all backgrounds.”

Mullen called the playdate a "huge privilege" and had nothing but glowing words for the Cambridges.

"In a way all we did was talk about babies. The Duke and Duchess were lovely, they were both very relaxed and we chatted about our experiences as first-time parents," he told the Independent. "He is a lovely little boy, very intrepid. The whole thing has been a huge privilege. It was lovely to meet the Duke and Duchess and share our beautiful children with them.They are both very lovely and loving parents."
