Recreational fishers collected a total of 2091 kingfish lengths including 1287 (62%) from released fish.  Otoliths from 460 fish were aged using thin sections to create an age-length-key. Kingfish started to recruit to the fishery (75 cm) as three year olds and were fully recruited at five.  The maximum age observed was 24 years. The absence of teenage fish gave high Z estimates  of 0.77 in East Northland and 0.34 in Bay of Plenty.  Total mortality corresponding to 40% SSB/R is estimated.
