According to Napier Port general manager infrastructure services Michel de Vos, the GPK – a backhoe dredge operated by Heron Construction – arrived from Lyttleton today and dredging will commence this week.

“The community will be able to see the GPK in the harbour for the next 18 months or so,” said Mr de Vos. “Some dredge plume may be visible as Heron goes about their work. This is sediment from the seafloor and is a normal part of the dredging process.”

Napier Port is monitoring water quality in real-time to ensure the dredging doesn’t harm the marine environment, in particular fisheries and Pania Reef, which is a site of cultural significance and an important breeding ground for kai moana.

“We’ll be alerted immediately by our monitoring buoys at Pania Reef if turbidity (water quality) is above expected levels and will adapt our operations, or stop, until conditions mean it’s safe to resume,” added Mr de Vos.

The Port will deposit most of the dredged material at a consented site 5 kilometres east of the port.

The Harbour Master has issued a notice to marine users to extend the marine exclusion zone around the port to keep vessels safe.

All vessels not associated with the dredging operation are asked to stay 50 metres away from the dredge.
