"It's nothing personal against Tommy - he's a top player and a really good character," Hudson said. "I respect his situation but there was a situation before that, and before that. I have to do what's right for the team."
Some would argue the inclusion of Smith was in the All Whites' best interests, given his quality has never been in question. But with precious few fixtures to prepare for the all-important 2018 World Cup qualifying campaign, the coach and player's priorities were too far apart.
"Tommy's (club) career is a priority and that's fine," Hudson said. "But I'm the coach of New Zealand and I have to do what's best for the national team. This decision's been very difficult but we have to over-achieve to be successful and, to do that, we need a consistent group of players who want to fight for the national team."
Smith forms a stark contrast with Winston Reid, his one-time centre-back partner who has also been left out of the side heading to Papua New Guinea at the end of the month. Reid was available for selection but the West Ham defender has simply suffered too many injuries to cope with another arduous campaign.
"Winston is 100 per cent committed," Hudson said. "We'd love him here but it's just not realistic for him to come right from the end of a long season."
Missing Reid and Smith, Hudson attempted to lure Andrew Durante out of retirement, but that door remained closed. Glen Moss' eye surgery dealt another blow to the All Whites' rearguard and the eligibility saga again reared its ugly head to account for the absence of Ryan De Vries.
But Hudson, understandably, wanted to focus on the players that were picked, insisting he was confident of claiming the tournament and consigning the horror in Honiara to history.
"I'm bored of talking about all the excuses," he said. "We have a good squad and they're more than capable of going there and getting the job done."
