Although Clark said the Government agreed with the "direction of travel," it has yet to accept any of the recommendations laid out in the report.
But, speaking to reporters this morning, Clark said he was "absolutely committed" to reducing the number of DHBs across the country.
"The direction of travel is very clear and the opportunity is huge."
He said the reforms would "certainly" be a key part of the next Labour Government's reforms.
The Government would legislate for any of the recommendations it chooses to adopt after the election, if re-elected.
Clark is sounding markedly upbeat about the likelihood of the recommendations becoming law.
He said the creation of a new health agency, as well as the reduction in overall DHB numbers, would help fix the woeful financial positions of DHBs.
According to the 2020 Budget, the Treasury is expecting DHB deficits of $1 billion a year, for the next four years.
In fact, the Budget said: "There is a significant risk that DHBs' deficits may be higher than what has been included in the fiscal forecasts, which would adversely impact the Government's operating balance and net core Crown debt".
Clark said the changes to the health care system – as proposed by Simpson – would help stem the fiscal bleeding.
"I expect DHBs to return to surplus over time."
Greens health spokeswoman Julie Anne Genter said local democracy is a core value for the Green Party and, as such, the party was opposed to the recommendation to scrap DHB voting.
"Local communities, and the health workers and their unions that serve them, must be fully engaged in the decision making steps following this report."
