A Hamilton doctor accused of misdiagnosing a woman's bowel cancer told a hearing he did "the work of 2.2 doctors" and often put in 100 hours a week.
But despite his long hours Dr Suresh Vatsyayann said this did not compromise his patients' safety.
Dr Vatsyayann, who was struck off the medical register in April for falsifying records, is defending allegations against him at a Health Practitioners Disciplinary Tribunal in Hamilton that he failed to diagnose a woman's bowel cancer.
A Health and Disability Commissioner investigation found he had breached the Code of Patients' Rights by failing to make the proper investigations with his patient.
The hearing resumed in Hamilton yesterday after a five-month break after Dr Vatsyayann called for an adjournment because of illness.
