In the 1600s the Dutch landed on the, but these foreigners didn't make any settlement efforts until the 1800s. These settlers, primarily British, brought their own foods to Tonga as they introduced cattle, chicken, wheat, potatoes, cassava, watermelons, pineapples, papayas, oranges, mangoes, onions, and tomatoes among many others. These foods added to the local diet and gave these foreign settlers a familiar diet, but most locals still relied heavily on their historic diet.
Through the 1900s few large culinary influences changed the diet in Tonga, although better communication, transportation, and technology gave the people access to imported foods and non-perishable goods, which extended the shelf life of many foods. Today these foods make an impact on the diet as canned meats are common and western foods and restaurants are popular, particularly those catering to the tourists. However, the locals tend to maintain their historic diets.

When & Where to Eat
When and where the Tongans eat is somewhat individual as different people and different jobs dictate when and where people eat more than the culture does. Generally most people eat a small breakfast at home, food that is usually leftovers from the prior day's meal.
Lunch was always the largest and longest meal of the day in Tonga as people would return home to eat a large meal and perhaps take a nap afterwards, perhaps to avoid the hottest part of the day outside. This is still common in many villages, especially among farmers, fishers, and others who spend their time outside. In most places lunch has become a shorter meal as most people eat at work.
For the workers who eat lunch at work, dinner is the largest meal of the day now and it tends to be a large feast with the family. Often times there is enough food made for this meal and the following day's breakfast and lunch. For those people who have a large lunch, dinner tends to be a bit smaller and usually consists of the leftovers from lunch.
Dining Etiquette
Dining in Tonga is fairly relaxed and it is difficult to insult or offend the people, but there are some rules that you must be aware of to spare yourself and those around you some embarrassment. Generally, if in doubt look to your host for clues, but some things are up to the guest to lead and this may be you.
The formalities and most important aspects of dining in Tonga are related to behavior more than actual eating. For example, bringing food to a dinner, even a small side dish or dessert is a great offense to the host by indicating they will not prepare enough food for everyone. Guests are also asked to sit in the middle of the table so they may converse with everyone more easily, but let your host seat you none-the-less.
Once seated, and you must be sitting to eat, you may notice silverware (cutlery) or it may be absent. Many of the Tongans eat with their hands and if this is the case do the same, although they may offer you a fork or spoon. As you begin taking your food be aware that taking a second serving is rude so take everything you plan to eat before you begin eating (even if this plate is huge as many of the locals will do). More importantly, be sure to try every dish offered.
Once everyone has their food, the eating pace is up to the guest of honor whether or not he or she knows it. This means you should wait to see if anyone starts eating and if not, they are likely waiting for you to begin, meaning you are the guest of honor. In this case be sure to pace your eating with everyone else because no one will begin eating until you do and no one will finish eating until you do; once you finish eating everyone else must also stop and you don't want anyone to leave hungry.
Most of the people will leave some food behind then will take their excess food home for a latter meal. You are welcome to do the same, but as a guest your host may insist that you finish your food.
If dining in a restaurant many of the above rules also apply, but there will most definitely be eating utensils and the setting will be more formal (although will still be but less formal than most of Europe, Australia, or North America). The host of a meal is expected to pay for everyone present; if this is you tip at your discretion. Tipping is not expected in Tonga, but for good service it is appreciated and in hotels and restaurants catered to tourists it is becoming more common.
Celebrations & Events
There are a few foods and drinks commonly consumed at celebratory events and holidays and these events wouldn't be complete without these foods. The first, and perhaps most traditional of these is 'otai (or kava), which is a drink that is often accompanied by speeches and other formalities. Another important food in cultural ceremonies is pork as pigs were only killed and eaten for important personal events such as weddings and funerals; although today pork is more common it is still eaten at every important event.
Another important dish is lu, which is made from taro root, meat, and coconut milk. Again this dish is found at most important events, but is also eaten more regularly as it has become a dish served on Sundays in many houses.
A final food of importance is topai, which are boiled flour and sugar dough balls. This food, served with syrup and coconut milk, is a common funeral food, but primarily due to their ease of preparation as opposed to having any true cultural significance
Drinks
Today nearly any popular international beverage can be found in Tonga from juices and soft drinks to coffee and tea. These are gaining popularity, but for a more historic and traditional taste of the islands, try the kava or 'otai. Kava is made from the kava plant's roots, which are ground to release liquid, then water is added and the juice is drunk. This drink holds an important place in the Tongan culture, as does 'otai, which is made of ambarella or fekika juice (although other juices are used today) and coconut, which is mixed then chilled.
Beer is the alcoholic beverage of choice in Tonga; both imports and homemade beers, called hopi, are popular. Hopi is popular because the government limits who can buy alcohol and how much they can buy so home brewing has taken over much of the market. International brands of beer, liquor, and imported wines are readily available at hotels and restaurants for foreigners.
Generally speaking, the tap water is safe to drink in Tonga, but check with locals for any particular regional differences. Also, many people may have troubles adjusting to the local tap water as it will most certainly be different from what your system is used to.
