The NSW Waratahs have finally done a deal with former All Blacks winger Zac Guilford over a month after he was linked with the Super Rugby club.

The Waratahs announced on Wednesday that the 26-year-old will make the move to Sydney at the end of October on a 10-month contract.

Guilford will provide depth in the outside backs for the 2013 champions, who have lost Adam Ashley-Cooper, Taqele Naiyaravoro and Peter Betham to European clubs.
