Flight Plans in VFR NZ are pretty simple, even if your flying into large terminals its only an extra step.It costs me $8 to log a flight plan and i do it every time because to get anywhere in NZ you usually fly A)over water or B) over bush/mountains. I always set my SAR time no more than 30 mins over my first leg and update it enroute if i need to. i also fill up the whole enroute list with airfeilds AND waypoints, if i go down in the Tararua's (pretty rough terrain which have swallowed a few A/C) i want you to know where to start looking.
