He is proud to have presided over raising child immunisation rates and increasing elective surgeries. In an interview with the Bay of Plenty Times Weekend in June this year, he said his proudest political achievement has been to provide more cancer services for patients, from the funding of Herceptin for breast cancer patients to speeding up radiotherapy services.
Anyone who can improve services for cancer patients has my respect. As we have witnessed during the past couple of months, politics is a tough game and Mr Ryall deserves respect for serving the constituents of Bay of Plenty and the wider New Zealand population for nearly quarter of a century.
It cannot have been easy at times. It was not unusual to see him on television commenting on a major health initiative and then later running into him at a school gala at the weekend talking to people.
There have been over the years MPs who ultimately failed to win my respect. Brendan Horan, dumped from New Zealand First and who stubbornly stayed on as an independent until voters dismissed him last Saturday, is an example.
But Mr Ryall, who received his silver tray with 14 other retiring MPs this week, can leave Parliament with his head held high. He is on record as saying he tries to avoid controversy and I cannot recall him being involved in any trouble.
His parting advice to the new generation of politicians, such as Tauranga list MP Clayton Mitchell, is noteworthy.
"Work hard and appreciate the value of your team."
The rookies would do well to follow this advice.
I wish Mr Ryall all the best.
