Dr Ruakere Hond, a key member of the working party co-ordinating the event, said the wars were a critical part of Taranaki's history.
"For a long time it has been made invisible. A lot of people simply say there were some wars, the land became ours, let's move on and forget about it," he explained.
"But in actual fact it's incredibly complex, in the role of those wars in how Maori became disenfranchised, became impoverished really in this region through the loss of an economic base."
Dr Hond added that we all needed to have the same understanding of our history, in order to stop talking past one another.
The New Zealand Wars, or land wars, were battles between the Crown and some tribes which took place from the 1840s to the 1870s.
In Taranaki the conflict stretched from 1860 to 1881, ending in the invasion of Parihaka following its display of passive resistance.
This week's commemorations come just days after a government bill apologising for the Crown's actions at Parihaka passed into law.
Minister for Maori Crown Relations Kelvin Davis will be part of a government delegation, led by the Prime Minister, at the opening of the gathering at Owae Marae in Waitara today.
He says we commemorate wars New Zealanders fought in overseas, and it's only appropriate to do the same for wars fought in New Zealand.
"I think it's right that we know about our history, we learn about our history. I think it makes us stronger as a country."
