The delicious sweets at de Spa Chocolatier's pair Belgian chocolate with Kiwi ingredients and fruit fillings (among other delectable things). There's a small shop in Merivale Boutique, 121 Papanui Road. Their factory's on the way to Ferrymead Heritage Park and Sumner. Before the earthquakes you could watch the chocolatiers at work. That's currently not offered, but you can still buy from the factory shop.
