The decision is supported by the 26 Provincial Unions and is intended to ensure 15-a-side community rugby competitions can continue without disruption in all three traffic light settings.
Further Covid-19 guidance will be issued by NZR early next year, including for Small Blacks rugby and for players aged five to 11 years.
Increased vaccination rates in the rugby community remains a key priority and NZR is actively seeking to partner with health agencies ahead of the 2022 season to support vaccination uptake.
NZR General Manager Community Rugby Steve Lancaster said the decision provided the rugby community with a level of certainty ahead of the 2022 season.
"We've taken the time to review the Government and Sport New Zealand's guidance and what's clear is that vaccine certificates will be needed for fifteen-aside competitions to play with minimal disruption.
"Over the past couple of seasons the rugby community has dealt with a lot of challenges and cancellations. This decision gives some early certainty and will reduce the impact on teenage and senior competitions when there's unexpected moves between traffic light settings in 2022."
Lancaster said both NZR and the Provincial Unions were committed to providing rugby for all New Zealanders, in compliance with the Covid-19 Protection Framework.
"New Zealand Rugby continues to support the rugby community getting vaccinated as the best way to protect everyone against Covid-19. But we're also mindful that rugby is our national game, it brings people together and remains a huge part of our communities.
"We want to see rugby available to all New Zealanders so we'll work with the Provincial Unions to provide other rugby offerings that follow the health and safety guidance and comply with the Government's framework. There's a range of options available - like sevens and 10s - that work within traffic light settings and we'll know more about what that looks like early next year."
The Covid-19 Protection Framework guidelines for sport and recreation gatherings apply to the players, referees, coaches, management and support staff.
The framework also applies to spectators and separate guidance will follow from NZR for clubs and schools to implement these.
