Food prices, petrol prices and public transport prices have increased over the last several years:
Statistics New Zealand reports the following:
Food prices rose 1.4 percent in June 2011, reflecting a seasonal rise in vegetable prices. Annually, food prices were up 7.5 percent on a year earlier. This is similar to June 2010, when prices rose 1.3 percent for the month. The fruit and vegetables subgroup had the largest impact on food prices in June, rising 12.2 percent. All subgroups made upward contributions to the increase in the food price index in the year to June 2011. Grocery food (up 8.0 percent) made the most significant contribution. Fruit and vegetables (up 15.7 percent), restaurant meals and ready-to-eat food (up 4.5 percent), non-alcoholic beverages (up 8.1 percent) and meat, poultry, and fish (up 3.5 percent) also increased. Vegetable prices rose 23.5 percent and fresh milk prices rose 9.4 percent in the year to June 2011.  Furthermore, the New Zealand Consumer Price Index for March 2012 stated that Cigarette and tobacco prices rose 13.5 percent in the March 2012 quarter, reflecting a 14.49 percent rise in excise duty on 1 January 2012.  Petrol prices were the second biggest contributor, up 2.3 percent. The housing and household utilities group rose 0.7 percent, mainly due to higher rentals for housing (up 0.9 percent). Higher prices were also recorded for property maintenance (up 1.2 percent) and purchase of new housing (up 0.7 percent). In current national news, Bus, train and ferry fares are set to increase by up to 90 cents in Auckland. Train users will be hit hardest, with prices for one to four stage tickets set to rise by 20c each. A seven-stage ticket – the equivalent of a trip from Britomart to Waitakere – will go up 90c to $9.80, and six stage tickets will rise 70 cents to $7.90.
