Ms O'Neill said she always had a lot to say ... "but I've got nothing to say now".
"It's always been a real pleasure and as long as I keep going, I'll keep coming."
Next was staff member Eileen Edwards, who has worked at Okere House for 20 years.
"Man, that's a long time to be in any field today," Mr Austin said, presenting Ms Edwards with a voucher for a weekend away in Taupo.
"She's a really calming influence at this place ... done a stunning job," he said.
Mr Austin also had awards and certificates for Suzi Aki, for 16 years' service, and Joy Ngatuere, 17 years. He said it was "pretty special to be able to do what we've done today".
The awards were celebrated with a special afternoon tea.
