New Zealand-based Japanese jockey Taiki Yanagida is in a critical condition at Waikato Hospital, after a fall at Cambridge on Wednesday.
Yanagida, suffered head and spinal injuries after a fall while riding Te Atatu Pash, and was placed in an induced coma before being taken to hospital.
The 28-year-old was supposed to be taken to Auckland's Middlemore Hospital, but his condition has prevented that from happening.
Yanagida has been in New Zealand for five seasons after arriving from Japan, where his family are still based.
"Taiki's mother and sister will arrive tomorrow (Friday) at 8am from Japan," manager Ted McLachlan told LoveRacing.
"We will know a lot more tomorrow after his mother has been there and New Zealand Thoroughbred Racing have been good, paying and arranging for flights."
Yanagida transitioned to senior riding earlier in 2022, and has accrued 42 wins in that time.
