The district is divided between the administrative regions of Auckland, to the north, and Waikato to the south. It is administered from the town of Pukekohe. The district is mainly rural, with local settlements such as Waiuku and Tuakau supporting the farming industry. One industry of note is the factory of New Zealand Steel at Glenbrook, north of Waiuku.
The district is bounded in the north by the start of the Auckland metropolitan area and the waters of the Manukau Harbour. Awhitu Peninsula stretches up the Tasman coast to the mouth of this harbour. Here are located several holiday spots, such as Kariotahi Beach and Matakawau.
To the south, Franklin is bounded by the fertile lowlands of the Waikato Plains. In the east, the land rises to the Hunua Ranges, to the east of which is the coast of the Firth of Thames. In the west is the Tasman Sea. The Waikato River mouth is at Port Waikato in the south of the region. This is renowned as a good place for surfcasting.
