Thorn was cited after he lifted and dumped Smit on his back in the early stages of the test in Wellington.
Thorn fronted a hearing in Wellington yesterday morning, and admitted an act of foul play against Smit, copping a week off, though he was with the team when it arrived in Dunedin yesterday afternoon.
Upon landing in Dunedin to prepare for this Saturday's test at Carisbrook, Hansen said he was frustrated with the inconsistency of the judiciary.
"We all saw it out there.
There were a lot of things happening out there in the game.
You've got to wonder about the consistency of the citing," he said.
Thorn, who had a strong game on Saturday, had received a fair hearing, Hansen said, but it was frustrating for him to miss a game in Dunedin.
Mosgiel-born Thorn (33) was looking forward to playing in Dunedin, so was naturally disappointed he would not be playing, Hansen said.
Chiefs lock Kevin O'Neill, who trained with the team last week to cover for an injured Ali Williams, would join the squad to replace Thorn, but North Harbour lock Anthony Boric was likely to start the test on Saturday at Carisbrook.
"We've just got to pick up the pieces and get on with it.
Anthony has played two tests and that is a different level of spectrum to Brad who is a 15-year veteran of professional sport.
"But Anthony has stepped up already in the tests he has played."
It was a day of drama for Hansen (49) yesterday, as the former Welsh coach was coming to terms with not being allowed to apply to coach the Crusaders next year.
Hansen had met the NZRU board on Saturday morning, seeking a dispensation to allow him to take the Crusaders coaching role, vacated by now Wallabies coach Robbie Deans.
But the board announced yesterday the Mosgiel-born Hansen would not be able to have both roles.
NZRU chief executive Steve Tew said the board indicated both roles needed a dedicated focus and out of respect for Hansen, and, in particular, what he contributes to the All Blacks environment, it was felt that he needed to focus on one rather than two teams.
Tew said Hansen could no longer be an All Blacks selector if he became the Crusaders coach.
Hansen said yesterday he was obviously disappointed with the decision but it was time to move on.
He had a contract with the All Blacks until the end of next year.
He felt he had received a good hearing from the board.
"I wanted to do the job.
It would give me more coaching time and make me a better coach.
"But they've made their decision and I've got to cop it and move on."
He said his application to coach the Crusaders could not be compared with Deans, who was able to coach the Crusaders for this season, despite being appointed to the Wallabies job.
"The circumstances were different and the Wallabies were a whole different system."
Hansen said there were some sore bodies yesterday, as could be expected from a very physical test.
He said Ali Williams' ankle was sore as expected and he was a day-to-day proposition, although it was hoped he would be available to play on Saturday.
Wing Sitiveni Sivivatu has a bruised shoulder and is doubtful for Saturday.
