For those of you who dont know Port Waikato..there aint much in the way of shops etc ...there is: -The Wharf Store on your way into port, which has a 91 octane pump. - Cafe / Takeaways down by the surf club. Your nearest proper shops are 28kms back up the road at Tuakau , where there is a couple of Liquor wholesalers & a G.A.S which has 91 & 95 octane. for 98 Octane you probably have to back to Pukekohe
