Henare said this meant there was "no drama" in the decision to split.
He thanked his "awesome kids" for their love, understanding, and support.
The news has drawn support and well wishes from friends on social media.
"Such a courageous decision but I'm sure to the benefit of all concerned," one person commented. "Glad it was an amicable decision and will keep you and your family in my prayers my friend."
Another person said it took "a ton of courage to have separate chapters even though you'll still be very much in each other's lives somehow".
"Stay kind. Keep encouraged. Much aroha and support to you both."
