 Although St Peter's was to be less affected, Liston supported Auckland Grammar in its opposition to the motorway and the projected route.Auckland Grammar argued that the motorway was going to adversely affect "two great schools" and should either be abandoned or re-routed.However, one of Grammar's suggested alternative routes was to be "further down" Mountain Road, which would have taken the motorway either through St Peter's College or through the Catholic netball courts which were used by the college and are now part of it as the site of the sports complex.
