The state government promised to legislate in the new year to improve renters' rights and security following a promise by the state opposition to ban "no grounds" evictions and limit the frequency of rent rises if elected.

Better Regulation Minister Matt Kean said on Wednesday that the state government has been developing a package of legislation to improve renters' rights that would be introduced into parliament in the new year.

"No grounds evictions, retaliatory evictions, all these things are currently undermining renters' rights in NSW," Mr Kean said. "We want to make life fairer and better for renters in NSW.

"We're currently working on a comprehensive plan to provide renters in NSW with more rights."
