The Bank of New South Wales opened a branch in Blenheim in September, 1884, and at first it had premises in High Street. Its present building was completed in the early part of October, 1903. It is of brick and plaster, two stories in height, and stands at the corner of Market Street South and Charles Street. The bank occupies only a portion of the ground floor, and the remainder of the building is let to tenants. Mr. McFarlane was the first manager of the branch, and Messrs R. C. Tennent, E. J. S. Eckford, and R. W. Jenkins have been his successors.
