Within a couple of minutes near the end of this film, three of the five contestants from Season 1 of Taskmaster NZ (2020) appear. Angella Dravid is the airport check-in person who asks if Zoe is pregnant, Brynley Stent is the flight attendant who asks if she's in labor, and Madeleine Sami is the hospital midwife. All three interact with Zoe, played by Rose Matafeo, who was a contestant on Taskmaster (2015).
Many of the arbour related tree scenes were filmed in Auckland Domain, a large municipal park set in a dormant volcanic crater.
