Minister for Justice Heather Humphreys has published the outline of legislation to update the existing laws around garda powers.
The Garda Síochána Bill will provide a statutory basis for search, arrest, and detention.
The new measures include the introduction of a single power of arrest, which will increase the scope of garda arrest powers.
Gardaí will also be required to make a written record of a stop and search.
The garda caution will also be put on a statutory basis and the requirement for a written contemporaneous note of a garda interview will be removed in cases where it can be recorded by other means.
An Garda Síochána and other bodies will also have the power to require a person to provide passwords for access to electronic devices when carrying out a search warrant under this legislation.
Special measures will be introduced for suspects who are children and suspects who may have impaired capacity.
"The law in this area is currently very complex, spread across the common law, hundreds of pieces of legislation, constitutional and EU law.
"Bringing it together will make the use of police powers by gardaí clear, transparent and accessible," the Minister for Justice said.
