No, I think you can (but don't depend on just my word for this purchase!). You would just set the lights to the T setting (as if someone from the US were a "tourist" in New Zealand) and just leave them there. The manual makes no caveat about this being a "not the same as regular" usage condition (no mention of degraded performance/quality, etc.), just that this is the opposite setting from the non-tourist setting.
