Preheat the oven to 350 degrees F. Grease and flour two 9x5 loaf pans.
In a large bowl, mix the pumpkin, zucchini, eggs, sugars, butter and vanilla together.
In a separate medium bowl, mix together 3 cups (375 g) flour, baking soda, baking powder, salt, pumpkin pie spice and cinnamon together.
Slowly add the flour mixture to the wet ingredients and mix until just combined.
Coat the chocolate and the walnuts in the remaining flour. Fold into batter.
Pour into the loaf pan and bake for 45 - 50 minutes, or until a toothpick comes out clean when inserted in the middle. Cool the bread in the pan for 10 minutes before turning out onto a wire rack.
