A scoping review has identified clear gaps in asthma care for children and adolescents in New Zealand, and calls for more responsive, culturally grounded models to improve outcomes. The review included articles on asthma care for those aged <18 years published between 2014 and 2024, identified from MEDLINE, CINAHL, Scopus, PsychINFO, and grey literature. A total of 21 articles from health or community settings were analysed, revealing the following themes: (1) medications and adherence; (2) education and health literacy; (3) children and whānau experiences; (4) culture and beliefs. Persistent inequities in asthma outcomes and care access were noted, particularly for Māori and Pacific children.
