That's just an interline, same as UA tickets you on QF metal domestically when flying to the US out of an AU port they don't serve. They also cannot be ticketed from any POS other than NZ (airnewzealand.com.au simply says it's impossible to go to MAN, for example). Not only will you earn no status or points, but you'll be treated by BA as if you held no status with them as well which will not go in your favour during IRROPS as you'll be bottom of the barrel for priority. I'd personally treat that as if it wasn't a thing.
