Ryder's manager, Aaron Klee, said medical staff at Christchurch Hospital were slowly bringing Ryder out of the induced coma he was placed in after suffering severe head injuries.
Klee said "they're working on the level of sedation for the coma to a level where they can talk to Jesse and make him become aware and we got a thumbs up from him".
More than 40 people, including Ryder's partner Ally, held a candlelight vigil for the cricketer, who suffered a fractured skull and punctured lung in the late-night attack outside a Christchurch bar.
Ryder's family have praised police handling of the investigation into what they described as "a heinous crime." Detective senior sergeant Archer said police had studied CCTV footage of the attack on Ryder and had "a fairly clear picture of what took place." Ryder was first involved in a scuffle with two men as he left a bar in the Christchurch suburb of Merivale about 12.30 am on Thursday. He was then attacked by one of the men after crossing the road to the parking lot of a fast food restaurant. He suffered the most serious injuries in the second attack.
Police say as many as 10 people may have witnessed the attacks and they are still appealing to witnesses to come forward.
Archer said police had not established a motive for the incidents but did not believe it was related to cricket or that alcohol was a contributing factor.
