Taoiseach Micheál Martin has officially opened a 75-bed facility at Ushers Quay in Dublin city centre.
The Dublin Simon Health and Addiction Centre facility cost €38 million to develop and has a capacity of 100 beds, although only 75 are currently open.
Addressing service provision to homeless people on the streets of Dublin, Mr Martin said his preference is for well-established organisations such as the Simon Community do that work.
He said well-meaning people get involved but may not be able to sustain the effort and may not have the right solutions to offer to people.
Mr Martin did identify any group by name. He said he is aware community organisations or sometimes new organisation that tend to emerge.
"I've seen it periodically and I don’t want to too critical here, sometimes pretty well meaning people...with no real experience in the field enter into the field.
"There would a lot of profile around and it doesn’t sustain and sometimes the solutions may not be the right ones," he said.
He said he is not against new ideas and new approaches being put forward but prefers organisations with experience.
"The new broom might be seen as much more attractive than those who have stood the test of time over many decades. It's important to affirm experience," said Mr Martin.
He said experience in dealing with homeless people on the streets is key and he encouraged anyone who wants to get involved to do so through an established, experienced organisation.
