The late change of allegiance by a group of Tongan players was legal but if those players were trenchant about their views they should have declared those intentions much earlier. They let themselves and the sport down with their extra-time country swaps and so did some of their fans who stepped across the laws of this land.
Patriotic exuberance is a rare sporting commodity in New Zealand but when it morphs into reckless behaviour and violence it has to answer to the same laws governing everyone in this country. The police, players and leaders in the Pacific Island community moved to corral the activities and tomorrow that off-field reaction will be tested as much as on the surface at Mt Smart.
Inside that arena, Tonga needs their rock stars to be headline acts if they are going to send England out of the tournament.
Jason Taumalolo, Michael Jennings and Andrew Fifita need to dominate if they are to quell the talents of Sam Burgess, James Graham and Gareth Widdop and deliver another knockout blow.
Tonga's concentration tilted in the emotion of their sudden-death duel with Lebanon and they need to rediscover the last quarter venom they uncorked to ride over the Kiwis.
England have the measured tactical mind of Wayne Bennett while this is new turf for Tonga coach Kristian Woolf.
Their fans will generate most of the atmosphere with their red tide of enthusiasm. The question is whether Tonga can bring enough discipline and sustained class to ice that support. The heart wants it but the head has misgivings. What is Mate Ma'a Tonga's answer?
