I've made some Kiwi Pils (and drank a few in NZ) and most of them have been mostly pilsner malt with up to 10% carapils, they tend to be very light in colour. The hops you've chosen are good ones for the style but I'd use a bit more, maybe another ounce of late hops somewhere. Nelson Sauvin tends to be a bit dominant so I'd use twice the amount of Motueka to NS. My fave kiwi pils hop is Riwaka, I blend it equal parts with Motueka and half the amount of NS. I've pushed my bitterness up a touch too, it's creeping up above 40ibu's now which sounds high for a lager, but it needs it with the carapils.
