The two P class locomotives owned by the Railways Department were known as Kiwi and Weka and they soon passed to the ownership of others, allowing the P classification to be used again in 1885. Weka was the first to leave the ownership of the Railways Department in 1882, when it was acquired by the Wellington and Manawatu Railway Company, who used it for construction and maintenance purposes until 1898. It then came into the possession of the Manawatu County Council's Sanson Tramway, who operated it until 1922, when it passed into the ownership of a sawmill and was ultimately scrapped in 1932. Kiwi left the Railways Department's ownership a few years after Weka, just before the arrival of the second P class in 1885. It worked for a number of sawmilling companies throughout the North Island for over half a century, but was derelict in 1956.
