Ardern responded to Bridge, giving him a dressing down over the content of the question.
"Never ... never ... never ... that's not a polite question to ask anyone - I was about to say a lady - but anyone, actually."
After composing herself, she then said: "It's just a little touch-up, Ryan. No reason."
In an attempt to redeem himself, Bridge tried to justify his line of questioning, saying the role of leading a country can cause people to age and clarified he meant no harm.
"Looks good, Prime Minister. And I only mention the grey hair because you are the prime minister and it does tend to age people. No harm intended, all right?"
Ardern replied: "No, it does, it does, I fully acknowledge that. Yep. Thank you for the reminder."
The Prime Minister's new look came after Gayford tweeted he had helped dye his partner's hair as well as giving Neve a haircut.
"Helped dye partners hair and gave daughter a haircut with scissors I bought at supermarket for $6. Remarkably both parties still talking to me [sic]," he wrote on Twitter.
One follower posted back saying they hoped the person's hair he dyed was a "business partner" and not Prime Minister Jacinda Ardern.
Another commented: "Fair is fair Clarke, you now need to let Neve cut your hair."
