Welcome to the Polynesian Cultural Centre! You are entering a world of funs! My name is called Tera,
a Polynesian name which mean "the sun". I'm very glad you can come today and learn about some of the
amazing Polynesian way. As you can see, here behind myself is one of their boats. To build a boat like this,
you needed a very tall, straight tree. You first cut down the tree and remove the branch. Then you cut the
tree in half so you have two long pieces of woods. You use one piece to make the boat. Remove the inside
for a person to sit. Take the bark off the outside of the boat and puts oil on it so it will easily go through
the sea. Some Polynesian boats have sails.
