Bank of New Zealand

Bank of New Zealand (BNZ) is one of the four largest banks in New Zealand. Established in 1861, it provides retail, business, and institutional banking services through a nationwide branch and digital network. Since 1992, BNZ has operated as a subsidiary of the Australia-based National Australia Bank (NAB), while retaining a New Zealand board of directors. Headquartered in Auckland, the bank has played a central role in the country’s financial system, including periods of government ownership during the late 20th century. Today, BNZ remains a major participant in New Zealand’s banking sector, with a market share comparable to its three main competitors ANZ, ASB, and Westpac.
