There's concerns over the future of New Zealand's health sector, off the back of three high-profile resignations that took place this week.

Director General of Health Diana Sarfati confirmed on Friday that she was stepping down from the role - seven days after Health NZ chief executive Margie Apa resigned before the end of her term.

Earlier this week, director of public health Dr Nicholas Jones also said he would be concluding his secondment as planned in February and resuming his previous role in Hawke’s Bay.

Health commentator Ian Powell says these resignations share a point of commonality following a turbulent period for the health system.

"We have a Government that kind of side-lines complexity considerations, it goes for the simpler options. And the simpler options are usually the ones that are wrong."
