Question: When did the people who first settled the Delaware Valley come to the country which produced the show @Seven?

Passages:
At Seven, commonly stylised as @Seven, was a New Zealand comedy show where Petra Bagust and other comedians present the "real news" from the last 24 hours from New Zealand and the rest of the world. The show replaced "Campbell Live", a New Zealand current-affairs program for the Summer Holidays in 2009/2010 whilst "Campbell Live" took a break. "@Seven" finished for the 2009/2010 summer holiday break on 22 January 2010 and was replaced with the normal TV3 7pm show, "Campbell Live". "@Seven" did not return the following summer break instead TV3 screened re-runs of "Modern Family". Europeans came to the Delaware Valley in the early 17th century, with the first settlements founded by the Dutch, who in 1623 built Fort Nassau on the Delaware River opposite the Schuylkill River in what is now Brooklawn, New Jersey. The Dutch considered the entire Delaware River valley to be part of their New Netherland colony. In 1638, Swedish settlers led by renegade Dutch established the colony of New Sweden at Fort Christina (present day Wilmington, Delaware) and quickly spread out in the valley. In 1644, New Sweden supported the Susquehannocks in their military defeat of the English colony of Maryland. In 1648, the Dutch built Fort Beversreede on the west bank of the Delaware, south of the Schuylkill near the present-day Eastwick section of Philadelphia, to reassert their dominion over the area. The Swedes responded by building Fort Nya Korsholm, named New Korsholm after a town that is now in Finland. In 1655, a Dutch military campaign led by New Netherland Director-General Peter Stuyvesant took control of the Swedish colony, ending its claim to independence, although the Swedish and Finnish settlers continued to have their own militia, religion, and court, and to enjoy substantial autonomy under the Dutch. The English conquered the New Netherland colony in 1664, but the situation did not really change until 1682, when the area was included in William Penn's charter for Pennsylvania. The history of New Zealand dates back at least 700 years to when it was discovered and settled by Polynesians, who developed a distinct Māori culture centred on kinship links and land. The first European explorer to sight New Zealand was Dutch navigator Abel Tasman on 13 December 1642. The Dutch were also the first non-natives to explore and chart New Zealand's coastline. Captain James Cook, who reached New Zealand in October 1769 on the first of his three voyages, was the first European explorer to circumnavigate and map New Zealand. From the late 18th century, the country was regularly visited by explorers and other sailors, missionaries, traders and adventurers. In 1840 the Treaty of Waitangi was signed between the British Crown and various Māori chiefs, bringing New Zealand into the British Empire and giving Māori the same rights as British subjects. There was extensive British settlement throughout the rest of the century and into the early part of the next century. War and the imposition of a European economic and legal system led to most of New Zealand's land passing from Māori to Pākehā (European) ownership, and most Māori subsequently became impoverished.
