Although event portfolios have become an integrated part of destination development, a lack of empirical research into the nature of portfolio design exists. A case study was conducted in Auckland, New Zealand, to explore the nature of the applied portfolio strategy in the city. The findings indicate that Auckland employs an outcomes-driven approach which is characterised by the orientation on economic outcomes, an ‘agnostic’ attitude to the compositional structure of the portfolio, an intensive bidding campaign and leveraging strategies. The current city’s reputation awards, successful event bids and positive economic indicators justify this approach. The identified issues, including a supply-led nature of the event portfolio and its predominantly quantitative measures of success, call for a revalidation of the approach. The results of the study contribute to the ongoing discourse about the value of event portfolios and their sustainable design in different urban destinations
