He said the hotel operators allowed people on the premises to become drunk and allowed disorderly conduct on site.
Police were called to the hotel about 8.50pm on June 5 this year after a report of a person lying on the road unconscious.
When officers arrived, about 15 people were drinking and milling around the front of the hotel.
Police were informed by a patron coming out of the hotel that an assault had taken place in the garden bar.
The person was allegedly punched to the ground by a number of people and kicked in the head.
Singh came downstairs and said he was aware about the person lying on the road unconscious but denied knowledge of the alleged assault. He admitted having had a "couple of beers" but said he was not drunk.
Singh told the authority he was trying to sell the hotel.
"The breaches admitted by the respondents (Singh and the hotel) are very serious and the way in which the second respondent as owner/operator has operated the premises, at least until June 2016, is most unsatisfactory," the authority said.
Meanwhile, the authority has suspended the on-licence of Brauhaus Frings on Lower Dent St in Whangarei for 48 hours from January 5 to 7 next year for selling a glass of beer to a 17-year-old female patron.
The manager's certificates for Kayla Neilson and Gordon Leddy were suspended for 28 days from January 5 next year.
