"We are still learning about the species – we will always have more to learn – and so it is wonderful to gain some insight and peer behind the curtain," she said.
Shannon Campion, Nox's trainer, felt privileged to have witnessed the moment and described it as an incredible stroke of luck.
"There had been signs she was due to lay for a few days and so I knew it was coming, but I was feeling a bit anxious that particular morning and stopped what I was doing to check in on her.
"Imagine my surprise when I found her mid-lay! I was stunned. I hand-raised Nox, so I also feel a bit like a proud mum."
The team at Wingspan are currently fundraising for their new development, a conservation, education and research facility where visitors can experience these birds up close.
"A huge part of Wingspan's ethos is wildlife engagement so New Zealanders will feel empathy for the birds and look out for them into the future," Campion said.
"Nox is a wonderful advocate for her species."
