"It could be really simple like someone going about their daily lives or it could be an event or it could be sports, but something that's not been tampered with," said McGregor.
It's this kind of candid photography that won him the coveted overall prize of New Zealand Geographic's Photographer of the Year award, last October.
McGregor said it was both flattering and surprising to be awarded the top prize.
He explained how the diversity of his job as a photojournalist for Fairfax Media has allowed him a broad scope of subjects to work with.
"I cover everything from social issues, to business, to news, to sports, to environmental stuff, anything really," he said.
