Preheat the oven to 350 degrees F (175 degrees C). Place rice and water in a saucepan over medium-high heat and bring to a boil. Once the water is boiling, reduce heat to low, cover, and simmer for 20 minutes, or until rice is tender.
In a large bowl, mix together the cubed pork, rice and broccoli. Stir in the cream of celery soup and mayonnaise, then season with pepper and curry powder. Transfer to a 9x13 inch baking dish, and cover with aluminum foil.
Bake for 45 to 50 minutes in the preheated oven, until evenly heated through. Remove the aluminum foil for the last 5 minutes in the oven.
