The retail value of the vehicles is more than $8 million and all the vehicles will be sold via the Land Rover dealer network following the tournament.
James Yates, group general manager, Land Rover New Zealand, says the company was "extremely excited to be providing a fleet of vehicles to help with the organisation of the tournament and Land Rover's global leveraging programme".
"The comfort, space, and versatility that Land Rovers are renowned for makes them the perfect choice for VIPs to enjoy New Zealand's challenging terrain and spectacular scenery."
Land Rover's support of RWC 2011 and RWC 2015 builds on the company's long-term relationship with rugby. It has been the official vehicle of the British and Irish Lions, supporting them on their 2005 and 2009 tours to New Zealand and South Africa.
In Britain, Land Rover has been the official vehicle of premiership rugby since 2002, and is developing the grassroots of the game through the Land Rover Premiership Rugby Cup, a nationwide tournament for under 11s and under 12s.
