That's right. You can use the miles to buy an award ticket on NZ (I did that last month to AKL), but you cannot use the miles to upgrade a paid ticket.
I'm not sure about the post that you can upgrade LH flights with miles. I thought you could only upgrade LH flights with UA SWU's, and that on a standby basis. You might post on the UA forum...probably get a better response there.
