Alright kiddo, imagine you live by a beautiful beach and you love playing in the sand and swimming in the sea. But imagine one day, someone came and said that you can't play there anymore because they own the beach and no one else can enjoy it.
Now this is what happened in New Zealand a while back. A long time ago, the Maori people (the native people of New Zealand) used to live by the sea and they used the foreshore and seabed for fishing, gathering shellfish and other things they needed to live. Then, in 1840, the British came and signed a treaty with the Maori people called the Treaty of Waitangi.
This treaty promised to protect the Maori people's rights to their land and resources. But over time, the government passed laws that slowly took away the Maori people's rights to the foreshore and seabed, saying it was now owned by the government.
The Maori people were outraged and they protested, saying that the government was taking away their rights and not keeping their promise to protect their land. This became known as the Foreshore and Seabed Controversy.
Eventually, in 2004, the government passed a law that said the foreshore and seabed were owned by the government and no one else could claim ownership of it. This made the Maori people even angrier, and they protested even more, saying that the foreshore and seabed were important to their culture and way of life, and they should have a say in how it is used.
So, the government and Maori people worked together to come up with a solution. In 2011, they passed a new law that allowed Maori people to have a say in how the foreshore and seabed was used, and it recognized their cultural connections to it.
Now, everyone can enjoy the beautiful beaches and seas of New Zealand, and the Maori people's rights to their land and resources are being respected.
