The man accused of a double murder at his Mt Albert mansion will face trial in February.
Cheng Qi Wang is accused of murdering Zhuo "Michael" Wu, 44, and Yishan "Tom" Zhong, 53 on January 14.
Wang denies the charges, and his lawyer David Jones QC has previously said his client acted in self-defence.
He appeared at the High Court in Auckland today.
Crown prosecutor Aaron Perkins advised the court that seven witnesses will require a Mandarin interpreter and one will need a Korean interpreter.
