Mogens Poppe, an experienced GP in Ohope, and Tamarapa Lloyd, chief executive of the Tuwharetoa Maori Trust Board, both attended the fewest board meetings in the past financial year - eight out of 11.
Jacob Te Kurapa, of Murupara, was appointed by Health Minister Tony Ryall in February this year, and had attended three out of the five board meetings held since then.
Gail McIntosh, a Tauranga chartered accountant, was absent for four out of 11 meetings, but was excused by the chair.
Mark Arundel, Yvonne Boyes, Ron Scott and David Stewart were present at all 11 meetings.
Board member and chairman of the Bay of Plenty Health Advisory Committee Mark Arundel, of Bethlehem, told the Bay of Plenty Times he had not seen too many attendance issues, but it was "not critical" for members to be at every meeting.
"About 10 out of 11 board meetings would be about average. But people have things that happen in their lives [and] funerals are not uncommon."
Attendance issues had never impacted on the board, he said.
"Somebody who does miss a meeting, they might miss some discussion around an issue, but in fact they will have all of the papers anyway and they'll get the minutes afterwards. So it's not critical and the numbers present at meetings are well and truly covered."
That was why health boards often had more members than they needed, he said.
Mr Lloyd said he was unable to make all of the meetings because he had taken up the role of chief executive of the Tuwharetoa Maori Trust Board.
"The new role presented a number of immediate challenges which conflicted with the DHB board meeting dates," he said.
"Being a board member is an important role, however, I also work for a living and sometimes other priorities take precedence. I remain absolutely committed to the DHB and the health of Bay of Plenty residents."
Mr Poppe did not return calls by the Bay of Plenty Times.
