The Taoiseach has told the Dáil that he and British Prime Minister Rishi Sunak will do all they can to get the Northern Executive "up and running as soon as is possible".
Leo Varadkar said he spoke briefly to his British counterpart last week in Iceland "and discussed this matter", adding that they will meet again at a conference next week.
"We will be working together to do all that we can to ensure that the Assembly, the Executive, the institutions of the Good Friday Agreement are back up and running again", he said, adding that this is "the clear message" from the people of Northern Ireland.
He was responding to Sinn Féin leader Mary Lou McDonald who said it is "critical" that the UK and Irish governments work together on this.
No DUP 'ask' to restore power-sharing
Meanwhile, Northern Ireland Secretary Chris Heaton-Harris has insisted he has not yet received any "ask" from the DUP in terms of money for the restoration of the Stormont Assembly.
Speaking at the launch of the Trade NI report at Westminster, Mr Heaton-Harris said he wants to see Stormont back "as soon as possible".
Asked whether he has received any request from the DUP in terms of money around the resumption of Stormont, he said: "I'm yet to receive any ask from the DUP, but we've got talks ongoing this week and they'll continue, we will get somewhere at some point."
Asked whether there would be money available for a restored Stormont, Mr Heaton-Harris said it was imperative to get the Executive up and running first.
"I think we want to get the Executive up and running before we go anywhere near any other questions, because there is a desperate need to get the Executive up and running," he said.
"I've asked a lot of the Northern Ireland Civil Service, who are delivering public services in a certain way at this point in time.
"I think we've seen that people want their politicians to get into Stormont and start making political choices about how money is spent in Northern Ireland, and that's what we need to see."
Mr Heaton-Harris also congratulated Sinn Féin on becoming the largest party in Northern Ireland at local government after becoming the largest party at Stormont last year.
"It's a function of democracy, I congratulated them on a good result. I don't think it particularly changes the nature of how I engage with them," he said.
He declined to comment on his view as a member of the Conservative and Unionist party on that development.
"That's a general question for unionism actually, I'm a great believer that unionism is stronger when it is positive and we need to be very positive about what the union can bring to everybody, all communities in Northern Ireland," he said.
"I'm an English unionist, so I would struggle to define what it means for Northern Ireland unionism, but I just know the union is better and stronger when we are positive."
Following the Northern Ireland local government elections, Sinn Féin took 144 seats across the 11 councils, an increase of 39 councillors.
The DUP maintained its 122 council seats, while the UUP lost 21 seats.
The Alliance Party, with 67 councillors, is now the third biggest party behind Sinn Féin and the DUP.
Good Friday Agreement key to resolving NI Protocol row
Former Taoiseach Bertie Ahern has told the Seanad that the constitutional changes introduced by the Good Friday Agreement (GFA) are the key to resolving disagreements over the Northern Ireland Protocol.
"I am sorry, but the starting point in the debate today about the status of Northern Ireland is not the Act of Union" but the GFA, he said.
"This is our opening space", Mr Ahern added, during an address to mark the 25th anniversary of the agreement.
He warned that the constitutional aspect of the agreement "has tended to be overshadowed by the focus on the institutions".
While those institutions are "crucially important", and while he is "all for listening respectfully to the concerns of the Unionist community around the Northern Ireland Protocol and the Windsor Framework," he emphasised that "honouring the balance of the GFA is a two-way street".
If this is done "we will find a way to settle our differences equitably".
Mr Ahern said that he wanted to put this on the Seanad record.
Bertie Ahern also warned that "the contestation that gave rise to the Troubles is absolutely intact" and remains "real".
While he shares the general excitement about the road ahead, he cautioned that we learn the lessons of history.
