I am publishing my draft submission on CRA 2 early. Key points below:
The ecological imbalance caused by overfishing kōura (spiny rock lobster) in CRA 2 has led to the proliferation of kina barrens, devastating kelp forests along Northland’s east coast.
Kelp forests in the Hauraki Gulf could be worth up to USD 147,100 per hectare annually, far exceeding the $10.17 million export value of CRA 2. Kina barrens, by contrast, provide no ecological or economic value.
Fisheries New Zealand’s reliance on biased data, such as Catch Per Unit Effort (CPUE), underestimates kōura depletion. Independent research shows kōura populations, even in marine reserves, are well below natural levels.
The proposal to close commercial and recreational kōura fishing in the inner Gulf for 10 years is the largest fisheries closure ever suggested for the Hauraki Gulf Marine Park. However, fisheries independent data shows it’s not enough.
A new biomass target is precedent-setting and a significant step for Ecosystem-Based Management initiated by Sea Change – Tai Timu Tai Pari. A 3x BR target is essential to control kina populations, halt the spread of kina barrens, and restore productive kelp forests.
Independent data must be prioritised, and a precautionary approach adopted, including a full closure of the CRA 2 fishery. Further delays will only worsen environmental and economic losses.
