Once the Dutch arrived to Māori, it didn't go very well. They anchored their ships and immediately the natives started chanting at them. I am not sure if they left their boats but the next morning the dutch left Māori after the Natives killed 4 of their sailors. 

The explorers were not very nice to the natives, after a source says, “The Māori challenged the intruders with ritual incantations and pūkāea or pūtātara (trumpet) blasts, possibly to frighten away dangerous spirits. In response, the Dutch shouted and blew their own trumpets. They then fired a cannon, provoking an angry reaction.” So instead of leaving or trying to make peace they blew their trumpets and fired a cannon. They also named the place “Moordenaars’ (Murderers’) Bay.” Which was because they killed their sailors.

What did natives think of them? 

I believe the natives didn’t like them one bit, because of how they tried to challenge the intruders right away and even killed some of the intruders.

What happened because of the way your explorer treated the natives?

The explorers were treated for how they treated the natives back. By the next morning the natives killed 4 of the sailors. 

One person that can be compared and contrasted to for how he treated natives is Hernando de Soto. A source states, “De Soto let it be known that he would not let anyone stand in his way. De Soto enslaved, mutilated, and executed the natives, often without provocation. De Soto and his men were positioned in the surrounding woods in anticipation of an ambush. When the natives arrived, they charged. Some of the Indians were captured as slaves. Others were shot.” Kind of like how when Tasman arrived they immediately were challenged by the natives, but in de Soto he was the one who started it. The same source also states, “After this encounter, the Spaniards traveled west and came to the River of Deer. The natives destroyed their crops and burned their villages as they drew back, so that de Soto and his men could not use them.” This shows how the natives got their revenge for killing many, like how Tasman’s 4 sailors were killed. 

I think that if someone from his time period were to see his map, it would help them discover and visit those new countries, and give them an idea of what that area would look like.  I also think if someone were to see the drawings by Isaack Gilsemans they would have a better idea of what the people of Tonga would look like, and in other photos what their ships would look like. One of the drawings was named after the natives and how they were murderers which probably gave the people a bad image to others who didn't know them too. 
 
Image #1 is different from image #3 for many reasons. The first reason is their point of view. Image one is a point of view from an "outsider". It shows the ships of the dutch, and the bay of Tongatapu. But in the 3nd image it is showing the point of view from someone close to the bay/island. It is showing somewhat a point of view of the natives. The points are probably different to show the reasons they attacked on eachother. It might seem like the natives were cruel to greet them with hate and later on kill 4 of the dutch's sailors, but it is their island and they don't want to be colonized.

I believe this was a negative impact because after he discovered it wasn't a land of wealth he started commanding trading fleets to Thailand, and commanded a war against the spaniards in the philippines. 

One explorer that had a similar expedition was Francisco Vásquez de Coronado. He traveled to (Now known as) New Mexico, thinking there would be streets paved with gold, but instead found more than 500 families, living on sandstone and adobe. Like Tasman they were searching for lands filled with gold, but ended up disappointed when they got there and it was nothing what they expected.

GLORY- Another reason for Tasman’s voyages was glory. It might seem like all he wanted was money, but after he got back from his traveling he was “chosen by the governor-general of the Dutch East Indies, Anthony van Diemen, to command the most ambitious of all Dutch voyages for the exploration of the Southern Hemisphere. He was rewarded with the rank of commander and was made a member of the Council of Justice of Batavia.” Which was probably a second motive for him. If you were part of the company and had all of this fame, you would be able to travel more and make more money with it. 
POS/NEG/WHY? 

I think this was somewhat negative, because he later on tried to start a war, but also good because he did find a lot of new places on earth for the Dutch East India Company.

Unlike Tasman, Francisco Pizarro traveled to spread religion to South America in his first expedition in 1524.
