Three years after starting their family, Waititi and Winstanley welcomed their second daughter, Matewa Kiritapu, on Aug. 11, 2015, in New Zealand.
In 2022, Te Hinekahu and Matewa Kiritapu accompanied their dad to the Sydney and London premieres of "Thor: Love and Thunder," in which they both guest starred. Waititi's kids had small roles as Asgardian children. "I always encourage people to have their kids around because it's just a cool environment and it chills the crew out," Waititi told People about making "Thor: Love and Thunder" a family affair.
Waititi also revealed that some of the monsters in the film were based on drawings that all of their kids made. "I was typing the script and my daughter kind of leaned over and she was like, 'What's an oil monster?' That's like the first thing I could come up with [when] I was writing. I said, 'I have no idea. I just wrote oil monster, whatever that means.' And she goes, 'What do you think that looks like? Do you think it's spiky?' And then she draws this like snakey thing," Waititi recalled.
"And then Taika said to me, 'Tell your kids to do some drawings,' and they did some drawings," Hemsworth added. After they were finished, Waititi took the drawings and gave them to the artists working on the film so they could bring them to life. "They turned them into these fully rendered, wild monsters," Waititi said. "In some of the kids' [drawings], they were super colourful. So we toned those down. But yeah, that's why the monsters are so weird and look so cool. That's why the monsters look like they were created by kids."
