"Sea lettuce is a naturally occurring green algae that is native to New Zealand. Sea lettuce can cause problems for the community when it grows during summer months and is deposited on beach and foreshore areas in large quantities."
"Sea lettuce varies in abundance from year to year and place to place. Its presence is most strongly influenced by uncontrollable factors such as wind, tides and coastal currents which affect water temperature and natural nutrient levels."
