"Can't wait to have you back on the tele at 6pm as a reminder us women can do hard things. Sending you lots of love as you transition back to your work life," they added.
Another said: "Wonderful to have you on telly again. Hope the first day back was good."
In September 2021, Hayes took to Instagram to announce the safe arrival of her baby girl.
"The newest edition [sic] to our family, Amaya Violet Blaauw, arrived last Friday weighing 3.21kg," Hayes captioned the snaps.
"Where has the past week gone?! Jay and I think she's just beautiful and her big brother Marlow adores her.
She paid tribute to her partner Jay Blaauw as well, who "changes endless nappies, never gives up trying to settle Amaya, all while keeping Marlow happy and looking after for me.
Earlier last year, Hayes revealed she spent a "scary few days" in hospital after coming down with a mystery illness.
She shared a snap to her Instagram page letting her followers know she had been admitted to hospital on Sunday night with a "mystery infection and high fever".
"We thought our baby might be arriving a couple of months early too, but the wonderful team at Auckland Central Women's Health and Origins Obstetrics got to work and I'm now recovering," she shared.
