problem is then he might have played 6 tests in Aust if he was lucky, and most in NZ, where his record is, well, more Chris Martin than Gordon Greenidge... but yeah, great point based on knowing nothing about NZ openers, and nothing changes in terms of what I said - he's remarkably good in Australia, and strangely useless most other places (he is a much better player than his overseas record)
32.5 isn't bad average for opener overseas. Look around world cricket. A lot of openers averaging in 30's altogether.
