You can feed in your booking reference into the partner website, & it may pickup your flight, but config may not be available.
To select a seat on the other airline you call and ask air nz for the reference number for the other airline.
Every time you book a seat on another airline via nz or any other carrier I thought it generated another reference so you can then call the other carrier and give them the reference number so they can pick up the booking and then you can ask them for the seat you want. Best if you've had a look at the seat maps via seat guru or equivalent and choose your preferred 3. Just beware the other carrier may charge you a fee for seat select if you don't have some sort of status (carrier dependent of course). For SQ it just said aircraft 'variable' so I just asked for window.
When I booked QR but my QF FF# in it came up in my QF app which was nice and since I was booking through QR I got to choose my seat.
So seat selection isn't a big issue. It's certainly better to do it this way than book individual tickets on individual carriers where you are screwed if the inbound is late by less than 6hrs (where travel insurance should cover). If it's all on the one ticket then the airlines are responsible for sorting you out.
