The singer told Digital Spy that he hopes to put out a special edition of his LP Secret Codes and Battleships later this year, which will include new tracks and live performances.
Hayes said: "I haven't recorded anything new for a while but I can tell you that there is so much involved with this album. There might be a re-issue at the end of the year.
"I did a song for the album called 'Roses' with Walter A and we recorded at least one other song that is f**king amazing!"
He continued: "We didn't put it on the record because it didn't fit and I didn't want to put it out as a B-side because it's too good for that.
"There's another track I did with [producer] Carl Falke that I've kept back in a Katy Perry 'Part of Me' sense. We've also recorded a bunch of shows which will appear somewhere."
Hayes recently revealed that he had turned down the chance to reform his former band Savage Garden.
