In his video on Saturday, a barely audible Alsati said he was very tired but managed to thank everyone for their kind messages of support.
He is now in a serious, but stable, condition and Canterbury District Health Board said this afternoon he had been transferred to Auckland.
David Meates, Canterbury District Health Board chief executive, said 31 patients who were injured in the mosque attacks remain in Christchurch Hospital.
"Two people were well enough to go home and have been discharged today.
"There are still 9 people in a critical condition in intensive care," Meates said
We continue to transfer any that are well enough to go to other wards as we can. People injured in the mosque attacks are our priority for surgery and other specialist care over the coming days."
