I think you overcooked that one there Mike ^^
OP, where in NZ are you?
Your noise issues will likely come from using a high ISO (1600+). Your camera is pretty entry level so doesn't have the best high ISO noise performance, but then again it's pretty new so it shouldn't be bad enough to worry unless you're pushing it up to 3200 or more. Noise will be worse in the shadow areas of the photo, and is exaggerated if you brighten these areas in post.
Your lens won't be the sharpest as it's only a kit lens, but again it won't be terrible and it won't cause any noise, just (slight) overall softness.
