There is a small store on the Reserve called ''On the spot'' This store is very expensive as it's the only one in the area, I can recommed the real fruits icecream and frozen yoghurt they make on the spot, In 2017 the cost was $5 NZ dollars but deffnitly worth it. Because of the regions micro climate, the hot long days and cool nights make it the perfect enviroment for fruit to flourish. You will see fresh fruit being sold everywhere Make the most of the apples & berries!
Although there isn't a big chain supermartket here about a 15 minute drive away there are plenty to choose from in Motueka (Countdown, New world) so make sure you stock up on your way through. (Think BBQ, meat, cheese, salads, cooking oils, sunscreen) .If you need any camping / beach supplies there is a warehouse in Motueka, which is a department store in NZ where you can find whatever your looking for.
