new zealand driving

hi i know na opposite ng driving lanes/driver seat natin sa new zealand. we were supposed to travel with a friend who lives in nz so siya na dapat magdrive but circumstances happened kaya di na siya makakasama.

do you recommend na kami nalang magdrive kahit wala kami exp driving sa opposite side? or do you have other recommendation na pwede para makalibot kami around north island?
