He said the poor behaviour had cast a spotlight on New Zealand's 20 DHBs and whether there were too many, and the costs associated with boards and executive teams.
On Saturday the Weekend Herald revealed it cost about $66 million per year for just 444 chief executives, senior executives and board members to run the country's DHBs.
That amount did not include the hundreds of thousands of staff, or the senior executive and board members' spending.
Meates said DHBs, often the biggest employers in their region, were unlike other businesses for several reasons;
• DHBs can't close their doors - health is a 24/7 operation
• They can't put up prices or generate more revenue
• Demand always outstrips the ability to deliver.
Canterbury and West Coast DHBs served a population of 600,000 with a budget of $1.8 billion.
Compared to some of New Zealand's biggest businesses in terms of employees, the DHB was 11th largest behind Fletcher Construction with 18,600; Progressive Enterprises, 18,500; Fonterra, 18,000; Defence, 13,930; The Warehouse, 12,000; NZ Police, 11,980; K-Mart, 11,000; Air New Zealand, 11,000; Oji Fibre (Carter Holt), 10,500; and Spotless, 10,000.
"In anyone's terms, we are big. The nature of what we do is complex too. Ours is the business of caring.
"This is why it is critical that we have the right governance and leadership arrangements in place and robust systems underpinning what we do."
He said every one of the DHB's systems was subject to extensive external audits, credentialing and certification and health and safety audits, and that board committees played a critical role in monitoring performance.
"Sometimes health is challenged regarding a lack of collaboration across DHBs and other providers," Meates said.
Canterbury though had a history of organised primary care and strong relationships between primary and community services and secondary care, he said.
At the same time the South Island Alliance had enabled a shared electronic health record to now cover one million people in the South Island.
Meates pointed out that before DHBs there were 23 hospitals and health services, one Health Funding Authority and the Ministry of Health.
That was preceded by 23 Crown Health Enterprises, four Regional Health Authorities and the MoH.
Before that there were 14 Area Health Boards and even further back there were 30 Health Boards.
The Canterbury board will hear the results of its expenses audit at a meeting in mid-February.
In December the Weekend Herald revealed that chief executives spent $1.2m in three years on travel and training.
Meates was the fourth highest spender on $112,838 between July 2014 and June 2017, though that figure was for both DHBs he heads.
On Saturday Waikato District Health Board member Mary Anne Gill called for DHBs to be cut from 20 to five, even if it meant losing her seat, to free up what she calls wasted money on duplicated services.
