Manuherikia claim permission

Me and some of my friends are going up to Alexandra to cherry park from the 10th and were looking to take it as an opportunity to also do some panning and possibly run a small sluice. I wanted to enquire about getting in contact with the claim owner of that section of the manuherikia to see if I could pay to prospect on their for a couple days if not I would love some advice around where else to prospect around Alex if anyone has any info they are willing to share

thanks, Eben
