Mary Lou McDonald says she will "absolutely" co-operate with the PSNI investigation of breaches of social distancing rules at Bobby Storey's funeral.
But she has also said she doesn't anticipate being able to travel to meet them if travel outside Dublin is locked down from tonight.
"If the police want to talk to anyone, obviously people will go and talk to them," she told the Irish Independent. "They are carrying out a review. They need to crack on with it.
"I would absolutely talk to them if they wanted it. By the looks of things I am not going to be going anywhere, because the special situation in the city now is that we can't go anywhere. I won't be travelling anywhere."
She added: "But I have no issue at all in assisting the PSNI with their review. All of us have to assist them in their work."
A number of Sinn Fein politicians have been contacted by the PSNI over their attendance of the controversial Bobby Storey funeral while Northern Ireland was under strict Covid-19 restrictions.
The party confirmed a number of their elected representatives "have received letters from the police this morning asking them to present for voluntary interview".
"They will contact the police and co-operate with the investigation," the spokesperson added.
Asked about Michelle O'Neill's expression of regret about the funeral, Mrs McDonald said: "The worst experience of all was families who lost loved ones and had to bury them in the most extraordinarily difficult circumstances.
"I am not going to judge or criticise any family for the decisions they make in laying their loved ones to rest.
"I am conscious, and I was at the time, that there were big numbers lining the streets for Bobby Storey's funeral. It fuelled comment and criticism. Of course I regret that.
"The last thing you want is for people to be upset, and particularly surrounding the whole heartbreak. I don't want to see controversy around a funeral and a bereaved family."
It is understood around 12 members of the party received letters from the PSNI.
Police said they contacted a number of people, inviting them to attend voluntary interviews with officers at a local police station.
Those who have received the letters have 14 days to respond.
The statement was issued yesterday on behalf of DCC Mark Webster, Cumbria Constabulary in relation to the investigation into the funeral of Bobby Storey.
He said that an "initial" number of letters have been issued to those who have been identified as being present at the funeral.
"The letters are inviting these individuals to participate in a voluntary interview with investigating officers at a local police station," he said.
Hundreds of people lined the streets of west Belfast for the funeral in June and it was also attended by senior Sinn Fein representatives, including the deputy First Minister Michelle O'Neill and the Finance Minister Conor Murphy.
Their attendance sparked a row at Stormont, with other parties accusing Sinn Fein of breaching the coronavirus restrictions.
Both Ms O'Neill and Mr Murphy have denied breaching social distancing measures while at the funeral.
It is not yet known if they are among the individuals who have been contacted by police.

Well, that took a while. Deputy First Minister Michelle O'Neill has belatedly conceded "regret" this week over how her attendance at the Bobby Storey funeral fiasco undermined public trust in the Assembly's Covid rules.
