"At the end of the day it is a game and we're passionate about what we do and everyone needs to be respectful of what's going on.
"The people are passionate and that's all I can really comment on.
"I haven't really seen much of what's been going on.
"I just know that the Tongan and Samoan people are passionate about their cultures."
Blair's comments come after the Kiwis' tournament opening win over Samoa last Saturday was marred by seven pitch invaders running on to the field during a break in play in the second-half at Mt Smart Stadium.
That incident preceded a number of ugly street fights over the past few days as the excitement boiled over in the lead-up to tomorrow's showdown between the island nations at Waikato Stadium.
Emotions are also expected to run high on the field when the Kiwis take on Tonga in Hamilton next weekend.
Both sides will compete for a spot in the quarter-finals and there is added spice to the game following the defection of four former Kiwis internationals - Jason Taumalolo, Sio Siua Taukeiaho, Manu Ma'u and David Fusitu'a - to Tonga.
Tonga are riding a wave of support as their impressive line-up - also featuring NRL stars Andrew Fifita and Michael Jennings - walloped Scotland 50-4 in Cairns last Sunday.
