In September last year, an undercover inspector visited the Napier RSA on a Friday afternoon and asked barmaid Cheyenne Leach for a glass of wine.
Ms Leach asked her if she was a member of the RSA or any other club, a hearing was told last month.
The former police officer was asked to sign in when she said she was not affiliated with any club.
She filled in her details but left the form blank where it asked for details of the member hosting her.
Ms Leach completed the remainder of the form, identifying her as a guest of a club member named Loss.
"I have never met or spoken to the person described in the visitor's sign in book as Loss, I have never attended the Napier RSA as a guest of Loss," the inspector told the authority.
She averaged about 200 compliance operations a year since 2009. It was her second visit to Napier RSA. Her first visit in 2010 resulted in the suspension of its liquor licence.
Ms Leach told the authority she pointed to Loss, said he was a really nice person and was happy to sign visitors in.
Loss, a long-time club member, appeared before the authority, saying he was happy to have visitors as his guest.
He has poor eyesight and difficulty writing, so asked staff members to fill out the guest form for him.
He had no recollection of what occurred that day or of the undercover agent.
The authority preferred the evidence from the inspector to that of Ms Leach.
The authority quoted a previous decision, saying a "stern message" needs to be sent to clubs.
"Our experience is that, although few cases have been before us, there has been a growing number of concerns expressed about the way the clubs have been operating the licences in relation to the presence of members of the public on their premises."
Napier RSA remains open and its restaurant is unaffected by licence suspension.
