The young left-arm off-spinner Mitchell Santner has been named to replaced the veteran tweaker Daniel Vettori for Northern Districts Champions League Twenty20 campaign next month.
The Champions League Technical Committee have approved the Knights' request to replace Vettori, who was last week named in the official squad of 15 before a family health matter led the former New Zealand captain to unexpectedly withdraw.
The 22-year-old Santner stood out in the Knights' one day campaign last season, and scored his maiden first-class century in the Plunket Shield.
The Knights depart Monday for Bengaluru, where they will train and acclimatise for a week before representing New Zealand in their opening Champions League Qualifier against Southern Express in Raipur on 13 September.
The top two of four teams in the rapid-fire Qualifier progress to the Champions League main draw.
