Notes: Births exclude late registrations under section 16 of the Births, Deaths, Marriages, and Relationships Registration Act 1995. Births are based on births registered in New Zealand to mothers resident in New Zealand by date of registration. New Zealand area data is not rebased when boundary changes occur. Data before 2006 is based on boundaries for the year of registration. Data for 2006-2010 is on 2006 boundaries, 2011-12 on 2011 boundaries. From 2013, data is based on 2013 boundaries. Figures for the Auckland Council for March, June, and September 2011 year are estimated using a combination of 2006 and 2011 boundaries. Data has been randomly rounded to three to protect confidentiality. Individual figures may not add up to totals, and values for the same data may vary in different tables.
