I don't know. I wasn't at any of those games to determine if a vocal positive crowd was an issue.
Plus I don't understand the finer aspects of Union as I played League.
The gross points like a better scrum or lineout turnovers are obvious, but the finer points are not to me.
As a side issue, apparently the Indian crowd at the first cricket test last week were relatively omnipotent.
Cricket is to Indians as Union is to the KIWI's
