The number of patients being treated at hospitals across the country dropped to about 85 per cent today as the 20 DHBs cope without their junior doctors.
About 3000 district health board doctors who are members of the Resident Doctors Association started striking at 7am on Tuesday morning until 7am on Thursday.
National contingency planner for the DHBs Anne Aitcheson said the advance planning had worked well and people had also listened to requests to avoid emergency departments unless it was a genuine emergency so there were fewer people going through the doors.
"Overall there's been no major problems and things have really gone well."
As part of the plan more senior doctors were included on the roster for all specialities for past two weeks.
