An increasing number of boat skippers are breaching maritime laws and illegally entering the Poor Knights Islands Marine Reserve on Northland's east coast.
Nineteen infringement notices relating to the area were issued by Maritime NZ last year compared to five in 2016 and 10 in 2015. The notices also incurred fines of between $2000 and $12,000.
Most of the offenders were operators of visiting cargo ships navigating a direct line down the east coast of Northland to save time and cost — coming between the Poor Knights and the mainland, rather than diverting around the reserve, specialist investigator Nick Dowden said.
The high-status reserve is one of only two in New Zealand waters where large boats are not allowed. The other, also in Northland, is the Three Kings Islands Marine Reserve, 55km northwest of Cape Reinga.
Fishing from any boat is prohibited in the Poor Knights reserve and ships longer than 45 metres banned from the designated "area to be avoided".
