Ah I see, these packages are news to me.
The requirements look similar to the Chancellor's (without getting the Chancellor's scholarship). Being a NZ applicant you satisfy the criteria for domestic. Though the webpage says studying Y12 in Australia the way it shows the entrance marks implies NZ students are acceptable, being ATAR 99.85+ or NCEA 99 or A-Levels A*A*A*.
But on the wording on the left side, I suggest you write again to UMelb to 100% clarify their reply to you was meant for domestic not international applicant.
