The Blues have added Baden Kerr, Waisake Naholo, Bryn Hall and Kane Barrett to their squad for next year.
Both Hall and Naholo have represented New Zealand in the U20s and Kerr and Barrett have played representative rugby at provincial level, with Barrett captaining NZ Secondary Schools.
All four players will experience their first taste of Super Rugby in 2013 and can't wait, as indicated by Papakura-born, Kerr, who is a fly-half.
"The Blues is the team I've always supported, and to now be part of that squad under the pretty impressive coaching team is exciting," said Kerr.
Auckland number eight Peter Saili has also re-signed with the Blues for another campaign.
