It means the second Bledisloe Cup test will be played at Eden Park next Sunday, as fans will be allowed to attend.
The test would have been moved to Dunedin if Auckland remained at Alert Level 2.
NZR general manager professional rugby and performance Chris Lendrum says it's great news.
"Auckland fans missed out on both the North v South match last month and the Blues v Crusaders match so this is positive news that they will be able to enjoy Test match rugby,' Lendrum said.
