The local diet remained much as it had in the past throughout this colonization period, essentially creating two diets, one the locals ate and one the Europeans ate. These changes were slowly magnified throughout this time since the technology from the Industrial Revolution was beginning to reach the country and this strongly affected the foods of the Europeans. Due to improved transportation and storage methods, these Europeans had greater access to foods from Europe and elsewhere, only encouraging the divide between the diets of the two groups.
In recent decades there have been additional changes and additions to the cuisine, but most of these changes have affected the cities and coastal areas. Ethnic restaurants, including Chinese and Indonesian, are growing in popularity, especially in Port Moresby. Better technology has also changed the local foods and how they're prepared, shipped, and stored giving many foods a longer shelf life and giving the people greater access to a variety of foods. Despite this, the local diet remains tied to pork, yams, rice, and local fruits and vegetables, while the ethnic Europeans tend to rely on a more European-styled diet.
When & Where to Eat
Most people in Papua New Guinea start the day with coffee or tea and a small breakfast, such as cakes, pastries, fruit, or even fish and rice. Breakfast is usually eaten at home prior to school or the workday.
Lunch was traditionally the largest meal of the day in Papua New Guinea and for many people this is still true. For these people, lunch is a large feast at home with family, which can last a couple hours. The foods served for lunch tend to be local foods, including vegetables, fruits, fish or chicken, as well as rice; soups and dessert are also common. For the people who have a more rigid work schedule, most commonly in the cities, lunch tends to be smaller and is eaten at work, often times consisting of the previous day's leftovers.
For those who have large lunches, dinner is the secondary meal as it tends to be much smaller, often just consisting of leftovers from lunch. For those who eat lunch at work dinner tends to be the largest meal of the day and can go on for hours as many of the above mentioned foods are served. Dinners are often eaten in the home.

Dining Etiquette
Dining in Papua New Guinea is generally very relaxed as rules are scarce, dress is usually casual, and tardiness is expected (although business settings may be more formal). More importantly, the dining experience vastly differs across the country as people in Port Moresby may eat in the continental style and restaurants may appear no different than those in Europe. On the other extreme there are people in the villages who eat with their hands, sit on the ground, and caught their meal just hours earlier. Due to these extremes the most important thing to remember is to follow your host.
No matter the setting, most people arrive about 10-15 minutes late and you can do the same. If you know where you're dining prior to going out ask your hotel or a local acquaintance what the dress is for that place; some restaurants in the cities can be fairly formal and you should dress to match. Once there let your host show you a seat and follow their lead. Most people belief you are a guest in their country and they will go out of their way to cater to you and your needs. Return this favor by trying everything served to you and graciously accepting their hospitality.
How you eat is again a question as many people eat with their hands, but in the nicest restaurants you are expected to follow international dining etiquette, including eating in the continental style (knife in the right hand, fork in the left). As you may be overwhelmed with foods and may not like some of the foods served, it's nice to know few people care if you eat everything or leave some food behind, but again follow your host's lead and if eating with an ethnic Chinese be sure to leave some food on the plate when you're finished. You may also notice that in villages some food will be ignored; this is for the chief and his family so don't touch it.
Generally, if eating in a restaurant, the host is expected to pay for everyone present. If you are the host do not leave a tip no matter how good the service was. This is a request commonly made by the people of Papua New Guinea as well as tour companies based in the country; tipping creates jealousy and is not a healthy practice in the country and they prefer to keep it that way.
Drinks
Papua New Guinea has most international brands and drinks, especially in the larger cities. This includes juices, soft drinks, tea, and coffee. However for a more authentic taste of the South Pacific try kava or waild koniak. This drink (known as kava in most of the country, but as waild koniak in others) is made from the kava plant's roots, which are ground to release liquid, then water is added and the juice is drank. This drink gives a very relaxing effect, yet is not considered a drug in the countries of the South Pacific.
The most popular alcoholic beverage in Papua New Guinea is beer, however many of these beers are imports and many of the local beers are not worth special mention. Wine and liquors are also available in Papua New Guinea, but again these are generally imports and are primarily found in hotels and restaurants catered to foreigners.
The tap water is not safe to drink in Papua New Guinea, despite what your hotel or guesthouse may say. You should entirely avoid the tap water and items that could be made from or with the water, such as ice, fruits, and salads.
