The integration of cycling and public transport (cycle-PT) can provide additional transport modal choice and flexibility in the use of existing public transport and also increase cycling trips and transit patronage. A model was developed for forecasting demand for bike racks on board public transport and secure storage at stations and terminals in different contexts and for different public transport modes. The NZ Transport Agency's Economic evaluation manual was used to calculate the economic justification in terms of a benefit-to-cost (BCR) ratio for implementing cycle-PT in New Zealand's larger centres. Cycle-PT is economically justified in New Zealand with BCRs from 2 to more than 10 depending on the centre and the scenario. The implementation of cycle-PT in New Zealand's six largest centres could produce more than 1.7 million cycle-PT trips per annum. This research has provided sufficient analysis for practitioners to be able to systematically plan and evaluate the demand and economics for cycle-PT schemes in New Zealand.
