@eddieb, I saw that and got my hopes up. But when I contacted Rainbow Farms about early access and keys etc, they said that
“At this stage and I have been told it will be for quite a while longer that the road is closed for access.
Please refer to the website – http://www.rainbowhoney.co.nz for updates as they happen.
The rain has been very heavy and access there has been lots of slips that need to be cleared.”
(Pretty much the same as what Box.a.Bits was told).
