Van der Hoff persevered in his duties with determination. His extensive work made exacting demands on him. He visited Potchefstroom and Marico regularly, and in addition established congregations at Suikerbosrand, Onder-Vaalrivier (roughly the present Wolmaransstad, Bloemhof, Makwassie and Christiana), Pretoria, Draakberg (in the vicinity of the present Volksrust and Wakkerstroom), Klerksdorp, Losberg and Rustenburg. This meant that he was almost continually on the move, mostly by ox-waggon, in wild, dangerous, and often inhospitable parts of the world. On his journeys he twice fractured an arm and once fractured a leg, and for a time had to hold services while seated.
