Abstract
 The estimated year class strength (YCS) of 1+ and 2+ snapper  from a November 2019 trawl survey in Hauraki Gulf was well above the long-term average, whereas the February 2020 Bay of Plenty YCSs were well above average (1+) and about average (2+). Coefficients of variation for pre-recruit snapper were reasonable. Surveys used a stratified two-phase design optimised for pre-recruit snapper. These surveys may also have potential to monitor abundance of recruit snapper and other inshore species.
