20 Pounds Colonial Bank of New Zealand

The Colonial Bank of New Zealand was a commercial bank chartered in 1873 and operated largely out of Dunedin, serving the South Island's pastoral and mining economy. It collapsed in 1895 — one of several New Zealand private banks undone by the long agricultural depression of the 1880s and 1890s — and its business was absorbed by the Bank of New Zealand. Notes dated after 1895 were never formally issued, and any surviving examples from the late series almost certainly never circulated.

Bradbury Wilkinson produced the plates; their work for colonial issuers during this period was consistent and technically accomplished, though the £20 denomination in any private New Zealand series is inherently rare given the sum's limited practical use outside wholesale trade settlement.
