The main thrust of this seems to be to be more aware of our student's cultural backgrounds, and then modifying our pedagogy in an ongoing manner according to this awareness, to give the best educational outcomes. Generally, this is great. There are some differences in how a Christian might do this compared to how a non-Christian would.
This is also focusing on our requirements to fulfill Te Tiriti responsibilities (the Treaty of Waitangi).
From a Christian perspective (defining Christian as a follower of Christ according to the Bible) we would not take an approach that recognises the problem through the lens of Oppressor vs Oppressed, as this is a Marxist approach from a Marxist worldview. Likewise we would not use Postmodernism as a lens as it is a worldview that is opposed to the biblical Christian worldview.
However, there are aspects of these different worldviews which hint at areas we can consider, e.g. Postmodernism reminds us that different people see the world differently. We reject postmodernism, as it says far more than this as a worldview, but we can take a gentle reminder to be aware of the perspectives of our students.
Marxism seeks to overthrow Oppressors and put the Oppressed in power over the current regime, and it also seeks out oppression constantly, in order to categorise every interaction/relationship through the lens of Oppressor/Oppressed. Christianity again, rejects this worldview, but can be reminded that we should seek to free the Oppressed, primarily from their sin and everlasting fate, and that we should pursue justice in areas we find ourselves faced with in life, as we have time and ability to contribute (according to priorities which we make, guided by God's Word). We might consider the protest against abortion as a similar area of justice to help the weak and Oppressed who cannot help themselves.
When it comes to "systemic racism" we must be careful as this can be the use of the Marxist Oppressor/Oppressed lens to find a problem that is either non existent or is not as big an issue as the labels Marxists tend to want to give them.
We need to be careful of so-called Christian resources and secular research that pushes in the direction of seeing sexual orientation as a legitimate area for positive diversity. Likewise we need to be careful of similar that does not declare its worldview up front. If it does not it is either ignorant that there is another view on this, or it is seeking to insist that its own worldview is correct and any other is in error.
