This week, 52 fresh charges have been added, including dangerous driving occasioning grievous bodily harm, negligent driving occasioning grievous bodily harm and causing bodily harm by misconduct, most of them relating to the guests who were injured.
Police allege Button was driving too quickly and told passengers to 'fasten your seatbelts' before the vehicle lost control at a roundabout, slammed into a guardrail and tipped onto its side.
Button was released on strict conditional bail after spending one night in custody.
He is due to appear at Newcastle Local Court on August 9.
Kane Symons, Angus Craig, Rebecca Mullen, Darcy Bulman, Nadene and Kyah McBride, Andrew and Lynan Scott, Tori Cowburn, and Zachary Bray were killed in the crash.
