I've been Gold on velocity for a couple of years (but will loose that soon, not flying as much this last year), and got a status match last year with AirNZ gold and finally get to use that in a week (haven't travelled since Sep last year)
Going Melbourne to Chicago return on Air NZ next weekend
I'm trying to figure out whether to put points on AirNZ or Kris flyer
AirNZ - currenlty 0 airpoints 0 status
KrisFlyer - 22,689 elite silver

As far as I can tell, neither will get me enough to retain gold or AirNZ ( need 900 status exp 08/2020) or up to gold on Krisflyer Required: 27,311 by 31 Jul 2020 and not sure what I can do with 327 AirNZ airpoints
Journey leg Airpoints Status points
Melbourne to Chicago O'Hare 176.00 205.00
Chicago O'Hare to Melbourne 151.00 178.00
Total bonus 0.00 0.00

Am I best to accumulate the points with Krisflyer? Can I still use the AirNZ gold status to get in the lounge if I put the points on Krisflyer? I still have the AirNZ gold card and boarding pass for an AirNZ flight right?
