Pubs reopened to punters after the state's COVID-19 lockdown in March.

Even with less pokie machines on due to social distancing measures, gamblers still spent more than $3 million in June in the city's clubs and pubs.

The NSW Office of Responsible Gambling tries to minimise and prevent problem gambling, a spokeswoman said.

"The office, and the gambling help services it funds, will continue reaching out to the community to encourage people to get the support they need, particularly during changed conditions and changing gambling behaviours as a result of COVID-19," she said.

"Gambling Help NSW provides free, confidential support and advice for anyone experiencing problems with gambling, including support for family members and friends."

In June last year, there were 727 pokie machines across 37 venues in Tamworth - this year there are 712 across 32 pubs and clubs. That doesn't take into account machines that have been switched off due to social distancing.

The outbreak of COVID-19 means venues are responsible for ensuring clientele gamble responsibly, and adhere to restrictions, a Liquor and Gaming NSW spokeswoman said.

"The measures in the Public Health Orders and COVID-19 safety plans are designed to keep patrons safe in all parts of a venue, including gaming rooms," she said.

"One specific measure that relates to gaming machines is the requirement to keep gaming machines 1.5m apart, either through physical spacing or switching off every second machine.

"While there is an increased focus on compliance with the Public Health Orders and COVID-19 Safety Plans, venues must also be aware of and complying with their obligations relating to the responsible conduct of gaming and gaming harm minimisation more broadly."
