Several sites at Queens Park were intentionally damaged on Tuesday night.
It included the winter garden panels, a glass table which was donated to the city, toilets, signage and the glass window of The Cheeky Llama Cafe.
Manager Melwin Mathew said he was called on Wednesday morning by park staff to inform him that his business had been targeted and after checking the CCTV camera they saw three people trying to smash the window with a flagpole from the golf course.
He said the group did not take anything from the cafe.
"So on Tuesday night, at around 11pm, two people came up and smashed our window with a flagpole ... In our CCTV video, we see two people accompanied by a third person."
He said this was not the first time incidents had happened at the cafe.
Last year, someone broke into the shed behind the cafe and took some beer bottles and frozen food and at the beginning of the year, police found stolen cars in their carpark.
"I’ve been living here for seven years now and this is not the Invercargill I’ve come to know.
"But I think like in the last two years ... these things have started to become a bit more common and a bit more frequent.
"Especially when it happens in a place like Queens Park, which is a family place and is supposed to be safe.
"If police or if our government or whatever, they don’t take the necessary steps to stop this or control this — what’s next?
"This time it was a broken window at a public place.
"What’s it going to be next?"
Invercargill resident Stephanie Wilson was also upset as the glass table which was donated to the city as an art installation was a special place for her.
"I don’t think it is very good.
"A lot of people love to come to the park. It’s place a where people just take time to walk around with family.
"When my mum was sick, we came here and sat down at this table ... so it is sad to see [someone vandalise it.]"
"Our bollard lights and other floodlights have also been damaged."
She said all the damage was being repaired and the council was not yet sure of the cost of the damages.
"It is expected to be in the tens of thousands."
Ms Rain said the council had increased CCTV monitoring in the council’s park network, including Queens Park.
"We have installed temporary trail cameras in various locations for additional monitoring at the moment.
"We have a total of 23 CCTV cameras across our network.
"It’s incredibly disappointing to see this damage continuing to happen in our beloved park and we encourage anyone to report suspicious activity to the police."
