I was always puzzled by this claim. The Marine and Coastal Area (Takutai Moana) Bill
guarantees free public access in the common marine and coastal area which is pretty much all non landlocled beaches in NZ. I've only ever been to the 90 mile beach once and I can't really remember it but it seemed to me that it clearly fell into common marine and coastal area by default really. No one could legally ever charge for it. Access rights ie vehicles might change in order to protect the shellfish beds I don't know. Hopefully commonsense will prevail on that.
Ive often thought about how great it would be to design a type of four wheel beach pushbike with a cart trailer to ride down beaches. Why not start thinking about it now because the days of petrol guzzlers are numbered and this is on the radar whether we like it or not. Now Phil Kettles a legendary shed designer? Cmon Phil I'll invest in the company.
