Those who wonder why incomes in NZ are so much lower for various occupations compared with Australia only need to look at this table, taken from this webpage.
It shows the current status for 2019 and the projected figure for 2023 both in nominal US dollars and adjusted for what is known as Purchasing Power Parity which takes the local cost of things into account.
Australia ranks 11th highest and NZ is 24th highest. On a Purchasing Power Parity basis, Australia drops to 21st and NZ drops to 35th. Hmm.
But pure dollar comparisons don’t take into account ‘quality of life’, which for many is as important if not more so.
