Hi History Project
Probably not much good to you, but we are planning a major feature on the Waikato War later this year.
In the meantime there is quite a bit of information in our King Movement topic. Also there are a couple of Calendar events that have more detail on specific events: British forces invade Waikato and Maori surrender at Rangiriri
Other sources can be found on our NZ Wars Further information page (including a link to the Jamie Belich documentary about the NZ Wars on NZOnScreen website.)
Hope this helps
