Water charges will be suspended at the end of the current billing cycle in June according to the government chief whip.
Regina Doherty is encouraging people, including her new cabinet colleague Finian McGrath, to pay their bills until then.
The Fine Gael deputy also said the programme for government will likely be revealed on Thursday with junior ministries announced next week.
Regina Doherty says those who don't pay their water charges are breaking the law and the money will be collected.
