These maps show the percentage of the overseas born population by the number of years since arrival, for each territorial authority area and each Auckland board area at the 2006 and 2013 cenuses. ‘Years since arrival' give an approximation of overall length of time in New Zealand, irrespective of periods outside of New Zealand, as they are based on the census question ' If you live in New Zealand but were not born here ... When did you first arrive to live in New Zealand?'
The data for each area (that is, each number of years for each area) sums to 100%. In each case, the deeper red/orange colours denote the higher percentages, the paler yellow/pink/white colours denote smaller percentages.
