The majority of new cases continue to arise in western and southwestern Sydney. Of the new cases reported in the 24 hours to 8pm Thursday, 508 were from the South Western Sydney Local Health District and 424 were from the Western Sydney LHD.
There are now 979 COVID-19 patients in NSW in hospital - including 160 in intensive care and 63 on ventilators - but Ms Berejiklian said authorities were anticipating cases would rise in the next fortnight.
"The next fortnight is likely to be our worst in terms of the number of cases," she told reporters on Friday.
"But as I have said it is not the number of cases we need to be focusing on but how many of those cases end up in our intensive care wards and hospitals and how many people we have vaccinated."
In the regions, meanwhile, there were 60 new infections reported in the west and far west of NSW, including a record 11 in Bourke.
Seven new cases were recorded in the remote town of Wilcannia, which has a large Indigenous population, while infections are also rising in the Hunter New England LHD (11 new cases) and the Illawarra Shoalhaven LHD (13).
Thirteen new infections were reported in correctional settings, while 12 had not been assigned to an LHD as of Friday morning.
The Parklea prison outbreak now stands at 96 cases.
NSW reached a milestone of 70 per cent single-dose vaccination coverage in people aged 16 and over on Thursday. More than seven million jabs have been administered in NSW.
It all but guarantees NSW will soon enough reach double-dose vaccination for 70 per cent of the population, triggering the wider easing of restrictions.
