AIM: To provide an update for the assessment of discrepancies in ethnicity counts in the 2001 census and mortality data for the 2004-2006 period.

RESULTS: Using a total definition of ethnicity, census and mortality counts agree reasonably well in 2004-06 and resemble comparisons in 2001-04, except at younger ages where counts for Pacific and Asian ethnicities are up to a third less for mortality data.
