Gidday there EE!.
Pretty much, a Marae is the central point of all Maori community activities.
It is built on a site called a Pa.
The Marae is used for greeting guests to the Pa, (called a Pohiri), community meetings (called a Hui) and also for funerals (called a Tangi).
The Marae is a very traditional place and there are a lot of rules and protocols to be followed while "on" the Marae.
But, I could go on for ever and send everyone to sleep.
However, the laws here, with regard to this situation with the plumber not being paid and returning to repossess the equipment, would make the plumber liable to tresspassing and theft charges, as it is the guy that he was formerly employed by that he should be seeing about payment.
Besides, what would ripping all the work out solve anyway?. Duh!!
