Dear Sarah,
Thanks for the advice. If it helps expedite things at all, as part of my general fish, discovered the following info from the RWC 2011 site contact form.
As you can see, NZ rugby doesn't appear very wriggler friendly at all, compared to the approach taken at twickers, flaminio and the marvellous millenium stadium.
Still up for it though, so looking forward to Gullivers announcing their packages.
Thank you for your email & interest in RWC 2011.
Your daughter will need to have her own ticket for any game that she
attends.
Ticket prices for children aged 15 or under will be available within
Category D & the GA Price Categories for pool matches and the Bronze
Final, if available at the venue. Children's tickets will not be
available for the quarter-finals, semi-finals or final.
Please see the below link for prices of children's tickets for all pool
matches
