Its head of general and vascular surgery, Dr Andrew Connolly, said a leading reason for this was having a facility, the Manukau Surgery Centre, dedicated to elective surgery and separate from Middlemore Hospital, where most acute surgery was done.
"The separation of acutes and electives has been the jewel in the crown. It means our operating rooms and wards are ring-fenced for elective surgery."
Auckland DHB has adopted this model in part with several new theatres at the Greenlane Clinical Centre, and Waitemata is doing it with its soon-to-be-built elective surgery centre beside North Shore Hospital.
One patient to benefit from Counties Manukau's leading role is Ambica Rama, 69, of Pukekohe.
She had her arthritic right knee replaced by an artificial joint at the Manukau centre last week. Her left knee was done in September.
She waited about six months for her first operation and five for the second.
The Auckland board says in its annual plan that although it is committed to boosting elective surgery, it will become "increasingly difficult to achieve" because of the high demand for the aged residential care subsidy, which it is obliged to fund.
But elective services director Peter Lowry said the board would achieve the goal of boosting the amount of elective surgery, and the Government's requirement of total compliance by June with the six-month rules for first specialist assessments and surgery.
