We love it when we get told about marine pest sightings and so we were stoked to get a heads up from a member of the public who’d spotted something weird on the beaches around Whitianga after the storms in January.

New research is showing how autonomous underwater technology and artificial intelligence could dramatically improve how we detect marine biofouling, and stop invasive species before they spread.

The 2025 Annual Forum in Waikato convened marine biosecurity professionals, scientists, council representatives, industry stakeholders, and the public to discuss current challenges, innovations, and collaborative efforts in protecting marine environments from marine pests.

Reaching the next generation is key and New Zealand schools have a growing range of marine biosecurity education resources that help students understand marine pests, ecosystem health and their role as caretakers of the moana. 

Recently a boat owner asked the Island Cruising Association for advice about visiting marinas that follow the ‘6 or 1’ rule. The Island Cruising Association passed the query on to us at Clean Below? Good to Go. Here’s what they said.
