The Kiwis victory at the Olympic Stadium was as important as any the team have achieved in the past 12 months.
The 9-2 win on Sunday didn't attract the headlines or hype of the 2014 Four Nations triumph in Wellington, or even the drought breaking Anzac test earlier this year.
But it could be just as significant.
It was vital for the belief of this team; as much as coach Stephen Kearney and the squad have talked about their brotherhood and great culture, it wouldn't mean that much if this team became just the third Kiwis side since 1971 to lose the first two tests of a series in England.
And what about the effect it will have on the new players in the squad, like Jordan Kahu and Kodi Nikorima? It's great to feel welcome and part of the team, but to play a tangible part in a test victory infuses belief and confidence like nothing else.
