The arrest of Te RauparahaIn mid-1846, Governor George Grey decided to neutralise the Ngāti Toa threat in the Wellington region by arresting Te Rauparaha. Despite the fact that he had encouraged Maori to leave the Hutt Valley, Grey did not trust Te Rauparaha to remain neutral. He believed that removing Te Rauparaha from the area would weaken Ngāti Toa and assert his authority over the chief’s mana. He also wanted to avoid forcing Te Rauparaha into a choice between his nephew and the settlers.
