Gold Coast have retained forwards Eddy Pettybourne and Agnatius Paasi for a further two NRL seasons.
Kiwi-born Pettybourne, 27, joined the Titans in January on a one-year deal when he returned to Australia for personal reasons following a successful season with English club Wigan.
Paasi, 23, stays on having played nine NRL games since trialling for a contract last November and despite missing over a month with a foot injury.
