Chiefs assistant coach and Samoa technical adviser Andrew Strawbridge remains in a critical condition in Waikato Hospital.
Strawbridge was admitted to Motootua National Hospital in Samoa on Tuesday with an infection in his right eye, and his condition deteriorated rapidly.
He had fallen ill on his flight to Samoa to join the team ahead of their Test against the All Blacks on Wednesday.
He arrived in Hamilton shortly after 6pm on Friday and was transferred to Waikato Hospital.
He remains in a critical condition this morning after spending the night in Waikato Hospital's intensive care unit, according to a joint statement from the Samoa Rugby Union and the Chiefs.
Strawbridge's wife Laura and sister Susan have been at his bedside.
