Limitations of the data
Annual registrations for births may differ from the actual number of events in a given year due to the lag between the date of birth and the date of registration and a small number of events that may never be registered.
Births exclude late registrations under section 16 of the Births, Deaths, Marriages, and Relationships Registration Act 1995.
Changes to data collection/processing
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.
