Hook was born in
Christchurch on 4 August 1921, the daughter of Mary and Stanley Hook. She grew up in
Oamaru, and
St Thomas's Girls' Secondary School. During
World War II, Hook served in the New Zealand Women's Auxiliary Air Force as a radio operator. After the war, Hook began training as a nurse at Mater Misericordiae Hospital (now Mercy Hospital) in
Epsom, Auckland, and not long after entered the convent, although she initially resisted her calling. She nursed at the Mater from 1949, and was the hospital administrator from 1964 to 1979. She established the Mercy Spiritual Life Centre in Epsom in 1983, and served as director until 1990. She was then a member of the management team and was spiritual director at St Mary's Convent in
Ponsonby. When the New Zealand government reintroduced titular honours in 2009, she declined redesignation as a Dame Companion. Hook died on 12 January 2010, and was buried at Waikaraka Cemetery in
Onehunga. ==References==
