Academic integrity is about having honesty in your work. It means developing your own original ideas, knowledge and creations while acknowledging other people for theirs.
Plagiarism is using other people's work without acknowledging those people. For more information on how plagiarism is dealt with at AUT, see the AUT Academic Calendar.
This is too close to the original wording. Compare it to the acceptable paraphrasing where a range of strategies (changing the order or wording, using similar words and changing word forms) are used.

AUT has proofreading guidelines for student assessments. They provide guidance on the extent and limits of acceptable proofreading assistance.
Proofreading your own work (checking for and correcting spelling, punctuation, grammar, sentence construction and referencing) is part of doing your written assignments.
If you ask someone else to proofread your work, or if you proofread someone else's work for them, there are limits to what is considered acceptable proofreading. This is because students are required to submit their own work.
