NSW's three new coronavirus cases, close contacts that contact tracers missed, were out and about in the community while infectious, the state's chief health officer has admitted.
The new cases come as thousands of Sydney residents celebrate "Freedom Day" after being stuck in lockdown since before Christmas.
The three new cases, two linked to the Berala cluster and one to the northern beaches cluster, are all close contacts of known cases.
Chief Health Officer Dr Kerry Chant on Sunday told reporters contact tracers had only recently identified the three as close contacts.
