No new stock assessments are presented for snapper stocks. The assessments from earlier years are summarised below.
SNA 1
These stocks were last assessed in 2000. The status of the two sub-stocks differs.
East Northland
The base case East Northland stock assessment completed in 2000 indicated that the recruited biomass at that time was at about the BMSY reference point and is expected to exceed BMSY at the end of the twenty-year projection period (with 67% probability). This conclusion is robust to all sensitivities investigated, except when a low natural mortality was investigated. Even in this sensitivity, the stock is expected to increase to near BMSY at the end of the projection period.
Hauraki Gulf/Bay of Plenty
The base case Hauraki Gulf/Bay of Plenty stock assessment completed in 2000 indicated that the recruited biomass at that time was less than the BMSY reference point but expected to increase over the next twenty years under the current TACC and estimated levels of recreational and unreported catch.
It is expected to exceed the BMSY reference point at the end of the projection period (with 100% probability). This conclusion is robust to all sensitivities investigated. For SNA 1 as a whole, catches at the level of the TAC will allow the stock to incre
