This series contains a set of maps and plans created by the Wanganui City Council in the course of their contract work for other councils. Only a small number of the total sequence is held.
It was common in the 1970s and 1980s for smaller councils to contract required expertise from companies or other larger councils. The Wanganui City Council offered Town Planning support services to numerous councils, including Marton Borough and Rangitikei County. These maps and plans were created by the Wanganui City Council for Town Planning purposes for those councils.
Following the 1989 amalgamations the sequence of plans were split up and this group was inherited by the Rangitikei District Council.
