Pukemokimoki Hill was a prominent feature of the landscape, occupying the space now bound by Carlyle St, Thackeray and Faraday Streets. From the 1860s it was progressively mined for fill to use in reclamation work in the lower lying parts of Napier, especially the area that became Munroe St. By the late 1800s the site once occupied by Pukemokimoki was level enough to be used as a sports ground, and was the location of Napier's first international cricket match.
Part of the space was then utilised to house Napier's early sewage pumps and a destructor plant for the city's rubbish. In 1911 the powerhouse (now the Faraday Centre), was built to supply electricity for Napier's trams. As the second photo shows, the site looked a bit different then. The only recognisable feature now is the roofline of the powerhouse/Faraday Centre main building.
