NSW Health's data reveals two new detections of COVID-19 were made in two of the region's local government areas [LGAs] in the 24 hours to 8pm on Wednesday.

Four more have been found overnight, the MLHD confirmed on Thursday morning.

The MLHD has also moved to allay fears of further exposure sites in the MIA following the detection of a positive case at the weekend.

It was announced on Sunday that a new case had been detected in Griffith, in a resident from outside the district.

They are no longer in the MLHD.

"The [MLHD] can confirm there are no new locations of concern associated with a person who tested positive to COVID-19 in Griffith," a statement issued on Thursday said.

"One case is a resident of the Edward River LGA, is a household contact of a previously confirmed case and has been in isolation," the MLHD said in a statement.

"The second case is a resident of the Albury LGA and remains under investigation."

Three more COVID patients have been identified in the Albury LGA and one in the Greater Hume overnight and will be reported in the official figures on Friday, MLHD said.

Sewage surveillance has also returned positive results for fragments of the virus in treatment plants at Jerilderie, in the southern Riverina, and Lake Cargelligo, in the north-west.

Earlier in the week, the West Wyalong waste was also revealed to have COVID fragments, prompting the MLHD to urge people to come forward for testing.

A prominent Albury nightspot was listed as a casual contact venue on Wednesday afternoon, covering a six-hour window on a Friday night.

Anyone who was at Zed Bar in Dean Street between 5.30pm and 11.15pm on October 8 is considered a casual contact and must get tested immediately.

Testing is available in the following locations:

Six more people have died from COVID-19 - three women and three men from greater Sydney, Wollongong and the Nepean area.
