Aims. To find out whether New Zealand household expenditures on health
care services vary according to the income of the household. To compa
re expenditures on health care in 1987 with 1991. Methods. Information
about household income and expenditure on health services was obtaine
d from the Department of Statistics annual household expenditure and i
ncome surveys for the 1987 and 1991 financial years. Four categories o
f health expenditure were examined: general practitioner fees, dental
fees, optician and optometrist fees, and spending on all health servic
es combined. Results. Spending on health care is unequally distributed
across income groups. In particular, the highest income households sp
end six times as much on dental care as the lowest income households.
The difference between high and low income households in the amount sp
ent on all health services was greater in 1991 than in 1987. In 1991 h
igh income households spent 3.6 times as much on health services as lo
w income households, compared with three times as much in 1987. Conclu
sions. High income households spend substantially more on health care
than do low income households. Households appear to assign a higher pr
iority to medical care than dental care, although this may reflect the
lack of any state subsidy on adult dental care.
