Māori Development Minister Nanaia Mahuta then jumped to her defence
"I might step in there. The Prime Minister has been more worried about the substance of her character and I think that's what we will focus on."
Ardern is in Rotorua meeting with key leaders to discuss the tourism industry's recovery.
Gayford tweeted on Sunday: "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."
Yesterday, TV presenter Ryan Bridge was scorned by Ardern after he asked her on The AM show: "Why are you dyeing it anyway? Is it going grey or something?"
She responded with: "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."
