Art Green and Matilda Rice's Waiheke wedding underway - report

Art Green and Matilda Rice's relationship blossomed in front of the nation on The Bachelor NZ, but they've done their best to keep details of their wedding day under lock and key.

Multiple media outlets are reporting that the reality TV couple are tying the knot on Friday in a secret ceremony on Waiheke Island.

There's at least one clue to be found on social media, in the comments section of the couple's close friend and fellow TV presenter Amber Peebles' latest Instagram post.

An old photo of Peebles and husband Brooke Howard-Smith at their engagement party prompted Rice to comment: "love you guys". Peebles response appears to hint at her friend's upcoming nuptials: "Love you too Tootles, can't WAIT to get celebrating with you," she replied.

NZME reports that Green's sister arrived in the country yesterday, having flown in from the US for the occasion.

Green and Rice met on season one of The Bachelor NZ in 2015, and have been together ever since. He proposed in Rarotonga in 2017.
