Hickey said she was worried about addressing the incident because it might encourage more attacks. She said she had experienced "a bad run" after having her hair pulled and being followed while out with fellow beauty blogger Shannon Harris.
Mr Nash said there were "some really bad people out there". "I would like to think that this is an isolated incident."
However, he said there were always people with tall poppy syndrome who were jealous of other people's success. He said it gave "Napier a really bad name".
In the post, Hickey called the Thirsty Whale "rough".
When contacted for comment the owner, Chris Sullivan, said he was told by police incidents were "well down in Napier bars".
He said he had no knowledge of the incident Hickey spoke of and if it did [happen] surely [the] complainant would have either advised us or rung police - neither happened.
"But a great way to get attention - and three months later, come on. Attention seeking."
Hickey said she was "shell-shocked" and tweeted she wasn't going clubbing any more.
"I was very scared because I'm not a violent person and it really rattled me."
Senior Sergeant Dan Foley said Napier was not a hot spot for violent activity and similar behaviour arose in most areas where there were alcohol and bars. He said the bars were run well and security guards worked with alcohol-harm officers.
Mr Foley said there had not been an increase or decrease in incidents. Both he and Mr Nash said the area was still safe and people should not feel threatened.
Mr Foley's main message was for people to stay together, look after belongings and keep each other safe.
Napier mayor Bill Dalton said police were doing the best they could with their resources.
"It's not specifically on our agenda but any rise in violence is something we will be very conscious of and something we would take action against, as much as we can as a local authority," Mr Dalton said.
