Township at the mouth of the Pelorus and Kaituna rivers and the head of Pelorus Sound, 43 km north-west of Blenheim. Havelock was the childhood home of two internationally important scientists, Ernest Rutherford and William Pickering. Streets were laid out in 1858, but it was the gold rush to the Wakamarina valley in 1864 that brought the township into being. Sawmilling was the principal activity until the 1910s, then dairying.

Meaning of place name
The township was named after British general Sir Henry Havelock to commemorate his role in suppressing a rebellion against British power in India.
