Guildford and Mathewson get All Black call-ups

Winger Zac Guildford and half-back Alby Mathewson have been called into the New Zealand squad as cover ahead of Saturday's second Tri Nations Test against South Africa in Wellington.

Richard Kahui injured his right shoulder when he fell awkwardly during Saturday's first Test success after coming on as a replacement for Joe Rokocoko - who himself suffered a hamstring strain.
