Educa has two different versions of the New Zealand Curriculum available for schools: Curriculum by Subject or Curriculum by Level.
By default, you'll see the curriculum organised by level. Site administrators can change to the subject view by opening the Curriculum page from the Tools menu
Simply check the box to activate the curriculum by subject and select whether the curriculum will be visible for stories and/or teacher portfolio posts. You'll also need to de-select the curriculum by level.
Your changes will save automatically, making the selected curriculum available to all teachers.
