Westpac says most of the 10,000 public sector staff who didn't get paid today due to a glitch in the bank's payment systems have now been paid.
In a statement this afternoon, the bank says: "Westpac can confirm that the majority of payments that did not go through last night have now been processed. The rest will be processed overnight.
"Westpac wants to assure all those who were affected that no one will be penalised. Any fees or charges incurred as a result will be absorbed or covered by Westpac.
"Westpac wholeheartedly apologises for the undoubted inconvenience this may have caused and totally understands the severity of the issue.
"A full investigation is underway to what caused the issue however our first priority was getting payments to everyone whose payments were not received."
