Enjoy the day at Chelsea Heritage Park and take time to join a factory tour. The Chelsea Sugar Factory took 18 months to complete and was built using one million hand-made bricks. These were made out of the clay, which had been excavated from the site. The current factory and Heritage Park are open to visitors and is part of the 5 Heritage Regional Parks near Auckland, day trip: guide by Best Bits.
