The Commonwealth Bank of Australia operated in Kavieng for seven years from 1916 through to the 31st of December 1923. The Bank of New South Wales (now known as Westpac Bank) operated in Kavieng from 1927 until the Japanese invaded during the Second World War in Jan 1942.
After the war, in 1945, it was some time before the banks returned to Kavieng and New Ireland. First the Commonwealth Bank of Australia and in the 1970's the Bank of NSW where today both Westpac Bank and the Bank of South Pacific are now operating, maintaining services that one way or another stretch back 100 years to 1916.
Prior to 1916 financial services were offered by the larger German companies to their commercial customers.
