I think all the teams normally wear the change strip in at least one pool game, to justify the sales of the replicas. It would be poor show to sell people a jersey that the team had never ever worn
NZR do not have an "away strip". They have a policy that the alternative strip is only ever used when there is a potential colour clash.
Occasions at RWC where the All blacks have worn the Alternative kit....
