New Zealand's traffic regulations place great emphasis on the safety of bicycle lanes to ensure the safety of cyclists. In New Zealand, drivers are allowed to cross bicycle lanes under specific circumstances:
1. Turning into a driveway: When turning into your own driveway or private property, crossing the bicycle lane is permitted.
2. Turning onto a side road: It is also allowed to cross the bicycle lane when turning onto an adjacent side road or street.
3. Parking: In certain situations, if a parking space is directly across from the bicycle lane, crossing the bicycle lane to park is permitted.
Therefore, the correct answer is 4. All of the above options.
