Two million years of movement in the Wellington earthquake fault
line underneath the Hutt Valley has helped form one of the
region's most powerful rivers. Today the Hutt River flows from
the southern Tararua Ranges through the Hutt Valley to the Petone
foreshore.
The Hutt Valley has been occupied since at least 1200 AD when
the Ngai Tara first settled there. They named the river Te Awa
Kairangi or "the highly esteemed river" as it was a
valued transport route and an important source of food. However, it
was also difficult to defend and has seen significant battles, loss
of life and a frequent change of guardians.
The first planned European settlers arrived in the summer of
1839-40, to be welcomed by Te Ati Awa. However, very few took up
the opportunity because prior to the earthquake of 1855,
the swampy nature of the Hutt Valley and its
frequent flooding made it relatively unattractive for
occupation.
This earthquake raised the level of the Hutt Valley as well
as the bed of the river, making the previously navigable river
impassable and draining the surrounding wetland. Settlement
increased slowly over the next 30 years, probably due to the
frequency of the devastating "old man" floods, during the
1850s and 1880s. During the 1880s the population of the Hutt Valley
increased rapidly but it was not until the mid 1890s that steps
were taken to prevent flooding.
Over 100 years later the Hutt Valley is a very popular
residential, commercial and recreation area. Still, its particular
geography - a narrow floodplain confined by steep valley sides -
emphasises the risks posed by the river. Greater
Wellington Flood Protection is responsible
for minimising this risk, particularly when the river
unleashes its full power.
