Waitangi day

Why are these people carrying this banner?

These people are protesting because they don't think that the treaty of waitangi is being honoured.

The treaty was signed on 6 Feb in 1840.Later that year over 500 more maori chiefs signed the treaty but the treaty was originally signed by about 40 chiefs.Because the maori didn't know how to write they used symbols instead.The treaty was signed waitangi which is up north in the bay of islands.The treaty was signed by the british settlers and the maori.There is a maori version and an english version of this treaty which caused some confusion to this date.

They are now debating which treaty is correct.
