The Bay of Plenty Polytechnic is abuzz with students enjoying their orientation ‘O' week.

Today there a variety of activities open to students at the polytechnic's Windermere Campus including mud wrestling and a t-shirt making competition.

Student experience intern Monique Lowry says the events planned for the week are about setting a positive tone for the year.
