This final section explores the physical infrastructures of port planning and development through analysis of two distinct areas. The first sub-section offers a case-study of the economy, traffic, and infrastructure of the Port of Genoa between 1861 and 1970 through analysis of traffic, cargo, and production statistics. It determines that the mixture of solid infrastructure and thriving maritime culture brought economic success to Genoa. The second sub-section compares and contrasts port planning and centralisation activities of Britain and New Zealand, particularly through the actions of the National Ports Council and the New Zealand Ports Authority. It demonstrates that centralised port planning was a failure in both Britain and New Zealand, but that this was due to a complex range of factors and not sufficient enough evidence alone to conclude that ports do not require some level of centralised guidance.
