"The social problems that are attached to homelessness and the cycle of homelessness are really the root cause of what we need to deal with,"Ms Berejiklian said.
"We know,unfortunately,that those who are prone to homelessness - even after you provide a roof over their head - need that wrap-around support of other services to ensure their opportunity for independence."
The state's progress towards the target will be monitored by the Institute of Global Homelessness,which will assist service providers to developer strategies and track results.
NSW is the 10th jurisdiction around the world to sign up to the insitute's program. The city of Adelaide has also signed up.
The City of Sydney,which collects data on the number of rough sleepers in the CBD,recorded 278 people sleeping on the streets in August - the lowest number in five years.
Social Housing Minister Pru Goward said one of the initial goals of the program would be to gather data on the number of rough sleepers,as homelessness figures for regional centres such as Dubbo were"not clear".
The target was welcomed by independent Sydney MP Alex Greenwich who said it would"kick start urgent action",but that it must be matched with"bold plans and system change".
