This report addresses using scenarios to identify climate risks for the primary sector, different modelling methods to quantitatively estimate risk impacts and the costs/benefits of adaptation options,.and reviews indicator frameworks used by the US, UK and EU. The report recommends that risk assessment should include a range of risk drivers, including physical and socio-economic and that an indicator programme is needed.

The fisheries taking FLA 3 are described for 1989–90 to 2018–19, based on commercial catch and effort data. FLA 3 includes up to 14 species, with three species predominating. Standardised catch per unit effort (CPUE) analyses were conducted on the FLA 3 species complex and on the three prevalent species. Finally, an in-season management procedure (MP), which set a TACC based on partial year CPUE, was evaluated for the period 2010 to 2019, the year the MP was suspended.

During 2019, the statutory reporting requirements for the inshore trawl fleet changed with the introduction of electronic reporting (ER) for the reporting of fishing activity, catches, the at-sea disposal of catches, and landed catches. This study provides a review of the catch and effort data collected from the inshore trawl fleet to evaluate the potential impact on the derivation of CPUE indices for a range of inshore finfish species.

A simulation testing framework was developed to evaluate and compare the performance of harvest control rules (HCRs) for 4 scampi stocks SCI 1, SCI 2, SCI 3, and SCI 6A. The harvest control rule evaluation (HCRE) framework uses CASAL stock assessment models as operating models and projects the simulated populations forward by applying an HCR each year to determine total annual catch. The framework is generalised and can be used with any CASAL model that has at least one CPUE index to project.

The Hauraki Gulf/Tīkapa Moana has declining health indicators. This review looks at the marine restoration potential in the gulf, with a particular focus on biogenic habitats. Terminology and frameworks used in the marine restoration literature are summarised, and the gulf’s past and present environmental history reviewed. Most biogenic habitats show loss, except mangroves. Knowledge gaps are highlighted, and suggestions are made for future research and management work.

This report provides estimates of changes in the recreational harvest from SNA 8 that could occur given incremental increases in the recreational minimum legal size limit and incremental reductions of the daily bag limit. These estimates are based on an analysis of boat ramp interview data collected over a 5 year period spanning the 2015–16 to 2019–20 fishing years. These analyses suggest that modest changes to recreational limits would have little effect on recreational harvesting from SNA 8.
