The average life expectancy isn't increasing so why increase the retirement age.
Statistics NZ would seem to disagree...
I think what they were meaning is that just because the average age maybe increasing, that doesn't mean that people are capable of working longer as a result . Also it is an average, but doesnt take into consideration that people maybe Ill with age related illnesses, where even though they may live longer due to drugs etc, it may not be a great quality of life. People can literally live for decades in rest homes and be totally out of it.
