Rugby World Cup organizers have revealed that 200 000 tickets for the world cup are still unsold just over two weeks from the opening match of the tournament.
World cup organisers have also said that they are 30.5 million New Zealand dollars ($25 million) short of their own revenue targets.
The IRB uses the money earned from the Rugby World Cup to fund the game around the world and a loss at the world cup could be detrimental to the game globally.
Organizers need to sell $219 million worth of tickets to meet targets, which will still leave a $32 million deficit on the cost of hosting the tournament to be met by New Zealand taxpayers and the New Zealand Rugby Union.
Rugby World Cup minister Murray McCully said that ticket sales are "pretty much on target" and he was confident of the revenue target being met.
Organizers are hoping a marketing push to attract more Australians would help ticket sales.
