It turned out to be a good call; Hayes, who celebrated that anniversary this September, has taken over from Hilary Barry as co-anchor of Newshub with Mike McRoberts and says the environment at TV3 has changed for the better.
"The newsroom at the moment is a fantastic place to be - there's a new momentum and energy. Things have definitely settled down."
As for what the next 10 years will bring, Hayes said while she doesn't know where she will be, she knows she'll still be in journalism - if she can help it.
"I can't imagine a world where I'm not a journalist. I don't know where I'll be but I hope I'm still working in the news. I learn something new from every story and almost everyone I get to meet."
