ANZ has seen a 30-percent increase in Pacific internet banking customers, which comes after Samoa and Kiribiti's nationwide lockdown, and recent Tonga events.
Banking has been unaffected by recent riots in the Solomon Islands.
ANZ banks in the Pacific are operational, in-line with government requirements with banks in Samoa back open tomorrow.
ANZ Regional Executive for the Pacific, Tessa Price said people can still access money in Tonga from their bank online or via ATM.
