To avoid plagiarism in your assignments, firstly, avoid copy-pasting and make sure to convey your thoughts in a logical manner. Additionally, add in-text citations using the correct references of the sources you have taken from the internet. You can even seek guidance from the Assignment Helper New Zealand (https://assignmenthelpers.co.nz/) services. Also use quotation marks to highlight the information you use word for word. Consider using tools like Turntin and Copyleaks to check for plagiarism. If detected, paraphrase your content. You can even use tools like Quillbot for this. Seek feedback from your peers and follow all the ethical guidelines.
