As a sign of respect to Wainui and his whānau, NZR have also asked the rugby community to come together to acknowledge his life prior to all NPC and Heartland Championship matches this weekend.
Players, coaches, managers and match officials will be wearing black armbands and Wainui will also be acknowledged via a special tribute and moment's silence prior to each match this weekend.
Wainui's whānau also thanked the rugby community and the New Zealand public for their "love and generosity" as the family continues to mourn his death.
In a statement to the media, a family spokesperson said: "We just want to thank everyone for their love and generosity. The beautiful tributes that have come from those who loved him all across the world means a lot to us all.
"We understand there are many hurting right now and wanting to hear from the whānau, but please respect that we have just lost our baby brother, a son, a husband and a father and our focus right now is healing and laying my brother to rest.
"Thank you all again for respecting the whānau's wishes."
