A wealthy, prominent New Zealand businessman facing indecent assault and corruption charges has failed in his bid to vary his bail conditions

The man, who has interim name suppression, has been on bail for more than three years, after initially being charged with indecent assault in February 2017.

The bail application sought to alter the condition limiting contact between the wealthy Kiwi and his business manager, who is charged alongside him with attempting to pervert the course of justice.

The businessman's trial is due to be held in February in the High Court at Auckland.
