Exploring Coastal Processes: Year 11’s Field Trip to Huriawa Peninsula and Karitane.

It was a picture-perfect day as 53 Year 11 students set off on their first geography field trip to the stunning Huriawa Peninsula and Karitane Beach.

With clear blue skies and a gentle breeze rolling in from the Pacific, the conditions could not have been better for an immersive day of learning outside the classroom.

The students have been studying a range of coastal processes, including longshore drift, wave action, and wave energy, all of which shape the dynamic landscapes of our coastline. On the trip, they saw firsthand how these forces contribute to the formation of key geographical features such as spits, erosion zones, stacks, stumps, bays, and headlands.

One of the most interesting discussions of the day revolved around longshore drift, a process responsible for transporting sediment along the coast. Watching the waves interact with the shore, the students observed this continuous movement by throwing tennis balls beyond the wave break, timing them, and recording the distance they travelled. This process plays a vital role in shaping landforms over time. The group also examined and measured the power of wave action by recording the number of wave crests and the height of waves, which they will later convert into energy calculations. This helped them understand how erosion carves out dramatic formations such as stacks and stumps, while deposition builds up features like spits.

Beyond the geographical exploration, the trip also provided an opportunity to delve into the rich history of the Huriawa Peninsula. The site was once home to a significant Māori Pā, offering insight into the strategic importance of the location and its role in Māori history. Standing on the peninsula, surrounded by breathtaking coastal views, students reflected on the resilience and ingenuity of those who once lived there.

By the end of the excursion, the students had not only deepened their understanding of coastal geography but also developed a greater appreciation for the natural and cultural heritage of the region. It was a day where learning truly came to life—an experience that will no doubt stay with them long after they return to the classroom.
