The New Zealand Rugby Union chief executive Steve Tew says the IRB judicial system could be better and it would have been nice if Andrew Hore's case had been heard earlier.
Hore has been banned for five weeks for striking in their win over Wales at the weekend.
Since then Hore and the team have been criticised for their silence over the incident which resulted in Welsh lock Bradley Davies going to hospital.
Tew says the SANZAR judicial system works a lot quicker with a duty judicial officer in place each week who can offer a penalty without a hearing.
Tew says they chose to remain quiet about the system because they didn't want to influence the hearing.
Hore misses this weekend's Test against England, three pre-season Super Rugby matches for the Highlanders and the opening game of next year's season.
