The couple, and guests, fight back tears as they exchange vows and rings, and swear to "be partners for life".
After the ceremony a group of male guests performed a moving haka.
On the charity page, Falwasser wrote: "Today my heart is heavy and sad, I lost my best friend, husband and the father to our son.
"I feel absolutely showered in love by friends and family, this is a hard time, however i do find my strength and refuge in everybody's support."
Falwasser said Navar's journey had just begun, she said. His body would now be taken to Kotahitanga Marae, "where he has asked to be laid to rest".
"He has impacted so many people near and far, and he will always be in our memories and have a special place in our hearts.
"As expected, costs to take Navar back home along with his immediate family have been quite extensive, and to give us every opportunity to spend our last moments spending time with him, we are asking for donations to assist with this. I am truly truly appreciative of your support."
The page has so far raised just over $85,000.
On Facebook the Nerang Bulls Rugby Club said it was holding an event today in celebration of Herbert's Life.
