This report summarises the protocols for producing the State of NZ Garden Birds 2017 | Te Āhua o ngā Manu o te Kāri i Aotearoa, which are as follows: (1) Securing the legacy of the resources required and generated when preparing and publicising the State of NZ Garden Birds 2017; (2) Editing the raw bird count data ready for analysis; (3) Calculating changes in bird counts for a subset of widespread garden birds at national, regional and local scales; (4) Using a standardised set of criteria to help the user interpret the results and readily identify changes of potential concern or interest; (5) Preparing eye-catching graphics for a non-specialist audience and publicised via multiple channels (media outlets, Facebook, Twitter, email); and (6) Inviting feedback on the resources from NZ Garden Bird Survey 2018 participants via an online questionnaire.
