In the summer, the barbecue is common, generally as a social event. Guests will usually be invited to bring beer (or wine), and on occasion meat, which the host will cook. Sometimes guests contribute a salad to the gathering instead. It is traditional for the men to cook the meat, and for the women to do everything else, although these patterns are changing. Similar Māori gatherings will often feature a hāngi, a pit in which meats or fish are cooked with vegetables. A deep hole is dug in the ground, lined with red-hot stones and covered with vegetation. The food is then placed on top. The whole oven is sprinkled with water and sealed with more vegetation. The hole is then filled with earth and left to steam for several hours. Traditionally, men dig and prepare the hole, and women prepare the food to go in it. All members of an extended family (whanau) help out for such a feast. The occasion is relaxed, friendly and fun, with people often eating the meal under a marquee.
