 The collection of long term age data is a requirement for countries fishing for Southern Bluefin Tuna.  This report describes the age estimation of otoliths collected from the New Zealand longline and recreational fishing sector between 2015 to 2018. A total of 361 otoliths were aged during this project. Age estimates ranged from 2-27 years and as in previous years there were few samples less than 4 years of age. No modal progression of age classes was observed with the age composition data.
