Will I be able to use the Internet?
This varies between hosts and usually depends on the location. Internet is limited and intermittent in NZ and unless you are in a big city very expensive. Many hosts are NOT big internet users, they may use only 3-4 gb per month, checking emails, wwoof site and a several other websites, so often will only have a small limited data cap to suit their needs and more often their budget.
It is important that WWOOFers check with hosts before or on arrival what their internet procedures are.
