The Kidds went to the Employment Relations Authoriuty seeking backpay for the work they carried out at the caravan park.
However, Member of the Authority T G Tetitaha found the Kidds were never employed by the Beaumonts, rather their work was carried out as volunteers.
Tetitaha said in his decision published this week he did not accept Mrs Beaumont told the Kidds they were volunteers.
"However there is equally no evidence either party intended this to be an employment relationship," he said.
There was no remuneration for their work, so no employment relationship was in place, Tetitaha said.
"Volunteers are the lifeblood of many communities. It is when workers are termed volunteers and receive remuneration that the possibility of an employment relationship arises. This is at the heart of the case here."
