Gardaí will be carrying out "intensive mobile high-visibility check- points" from today.
It comes as Level 5 restrictions are implemented across the entire country.
Gardaí will be engaging, explaining and encouraging people to follow public health guidelines, a spokesperson said.
They will also continue to engage in high-visibility patrolling in public spaces such as parks and other recreational areas.
Deputy Commissioner of Policing and Security, John Twomey, said compliance "must continue" until the public health crisis is over.
"An Garda Síochána's focus remains on helping to prevent the spread of Covid-19 by seeking public compliance with public health regulations," he said.
"Throughout 2020 we have seen high levels of compliance by the public. This must continue in 2021.
"Under Level 5, we are asking people to not make journeys unless they are essential. To minimise their contacts. To maintain social distancing. To wash their hands."
Mr Twomey said he wanted to remind people that not only will gardaí be policing, but they are also there to help, even if it is for a socially-distanced chat.
"I would like to remind people, particularly at this time of the year, that their local gardaí are here for them," he said.
"Whether that is collecting their prescription or some fuel or even a socially-distanced chat, please do not hesitate to contact your local garda station. We are here to help."
As part of Operation Faoiseamh, the public is reminded that the 5km restriction does not apply in the case of domestic violence or if a person is trying to escape the risk of harm.
"If you are a victim of abuse or know of a family member or friend who is a victim of abuse, that information is important to us," a garda spokesperson said.
"I ask that you make contact with An Garda Síochána."
