In New Zealand rugby fans are counting down to the start of the Rugby World Cup which begins on Friday and springing up all over New Zealand, are flash mobs - groups of people who get together to put on some kind of performance in public places without any warning.
The mobs are performing the Haka - the traditional Maori dance - performed by New Zealand's All Blacks.
