The Commission took proceedings against NZ Bus after it acquired Mana Coach Services because the acquisition would be likely to result in a substantial lessening on competition. The High Court found that NZ Bus had breached the Commerce Act and ordered payment of $1.1 million in penalties and litigation costs. NZ Bus and Infratil (NZ Bus’ parent company) appealed the High Court's decisions on liability, penalty and costs. The Commission cross-appealed the level of penalty ordered against NZBL and the Court's decision not to impose liability on Infratil. The Court of Appeal upheld the High Court’s decision.
