The bank acquired Clydesdale Bank and Northern Bank from Midland Bank in 1987, establishing a foothold in Scotland and Ireland. Yorkshire Bank joined the NAB family in 1990, extending operations in England and Wales.
The 1990s saw major international expansion with the 1992 acquisition of Bank of New Zealand, which commanded roughly 26% market share. Michigan National Bank became part of NAB in 1995 before being sold to ABN AMRO in 2000.
