"The really honest answer to that is, there was a story about a British family terrorising New Zealand, did you hear about that?," he said.
"There was a British family of tourists terrorising New Zealand, and [executive producer] Tim Carvell and I were emailing back and forth, going, 'actually, I wish we were back at work.' But all the other stuff that wasn't that? No, we were more than happy [to skip it].
"We had a couple of weeks off over the holidays, but otherwise, we've been working the whole time, researching stories, so there's been nothing in particular that really felt painful that we weren't on TV for, other than the barbaric British family in New Zealand," he added.
"It's really worth looking up, it's pretty amazing. I genuinely was disappointed that we weren't around to show people what was happening there."
