New Zealand uses strength gradings such as MSG (machine stress grade) or VSG (visual/verified stress grade) whereas Australia uses MGP (machine graded pine). The MGP grades are slightly different to the MSG grades and are not directly comparable.
New Zealand specifiers should be specifying MSG or VSG grades for New Zealand. Australian grades would have to be dealt with as an alternative solution under the New Zealand Building Code as far as the consenting authority is concerned.
