The Central West pop-up testing site will be hosted at Forbes Caltex, on the Newell Highway, and will be up and running later this month.

Minister for Regional Transport and Roads Paul Toole said the new sites will provide an easy way for freight workers to be tested.

"The freight industry plays a crucial role in making sure essential goods get where they need to go and these extra testing sites build on existing measures to keep freight workers healthy and safe," Mr Toole said.

"After discussions with the industry, we have established pop-up sites at Taree Service Centre, on the Pacific Highway and will shortly be opening new sites around Narrabarba on the Princes Highway south of Eden and near Forbes on the Newell Highway.

"From up north at Taree, out west to Forbes and right down south to Narrabarba, these new locations mean a majority of the key freight routes across NSW now have a pop-up testing site in place for freight workers.
