"One of the difficulties is that toheroa look very similar to tuatua. Tuatua are much more prolific than toheroa and are not subject to the same gathering ban," says Mr Rudsdale.
"Toheroa shells are more brittle and slightly rounder than tuatua and have a slight lump at the base."
Mr Rudsdale says toheroa have a major cultural significance as well and it would be a great pity to see their recovery fail because of people's greed or the fact that people are unaware of the rules.
"If you are caught with or have disturbed up to 50 toheroa, you face a $500 infringement fine. If you are caught with more than 50 toheroa, you face prosecution and a maximum fine of $20,000."
He said fisheries officers and honorary fisheries officers would be out and about on the beach and would be using discretion but would not tolerate people deliberately or repeatedly taking toheroa.
Mr Marsden supported the MPI's call for responsible management of toheroa on Ninety Mile Beach.
"Public use of vehicles doing wheelies and donuts on the beach is just as concerning as people taking more than their fair share of toheroa. Vehicles rip up beaches and destroy the toheroa because they sit at the high tide mark and not much deeper beneath the sand.
"It's about maintaining adequate toheroa numbers because they've been gone for so long and haven't regenerated," he said.
Mr Marsden said NgaiTakoto would be working with the Far North District Council and other stakeholders to put up signs warning people against taking the shellfish and to avoid driving on the beach.
With an increase in tourists and population in the Far North, he said people may be tempted to flout the rules regarding gathering of toheroa, tuatua and pipi.
