A fully integrated stock assessment is presented for HOK 1 modelled with two stocks (western and eastern) and with fish residing in four regions. The western stock is estimated to be lower than the eastern stock, with biomass expected to be 25–43% B0 in 2027 under current catch levels for the western stock and 46–55% B0 for the eastern stock. A simpler model with one stock and one region estimated current biomass to be 37–45% B0 in 2022. Target range for hoki is 35–50% B0.

Characterisation and CPUE (catch-per-unit-effort) analysis for SCI 1 (Bay of Plenty) and SCI 2 (Hawke Bay-Wairarapa) scampi (Metanephrops challengeri). Scampi live in burrows and variability in emergence rates impact the relationship between CPUE and abundance. SCI 1 index increased from 2016 to 2021. SCI 2 CPUE generally declined from 2015 to 2021. The CPUE indices were accepted by the New Zealand Fisheries Deepwater Working Group as valid for tracking scampi biomass for use in the stock assessment.

For southern blue whiting on the Bounty Plateau (SBW 6B), a new Harvest Control Rule, HCR2022, was developed that allowed for consecutive years with no acoustic surveys. HCR2022 replaced the previous HCR which required an acoustic survey every year.
