Preheat oven to 350°F (175°C). Grease and flour or line three 7×3 inch loaf pans.
In a large bowl, mix together pumpkin puree, eggs, oil, water and sugar until well blended. In a separate bowl, whisk together the flour, baking soda, salt, cinnamon, nutmeg, cloves and ginger. Mix in the dry ingredients until it is just blended. Pour into the prepared pans.
Take 1/4 cup nutella and drop spoonfuls across top of batter (1/4 cup for each loaf). Use a knife and begin to swirl nutella with batter, making figure eights across the batter several times.
Bake for about 50 minutes in the preheated oven. Loaves are done when toothpick inserted in center comes out clean. (The batter portion should come out clean, but the nutella will be gooey and stick to toothpick)
