What on Earth is happening in the Hurunui?

Whispers are filtering about of a gang related 'incident' at the Waiata Vineyard between Amberly and Waipara. Like any good rumour, just what the actual events are may be hidden behind a wall of silence.
Ironic that this McKean Estates Vineyard is a predominant source of noise pollution in the area and has been the subject of on-going complaints from locals over the presence of wind machines.
There has been lots of activity at the 365 Ha property that boasts 53 frost fans, the noise from which has been likened to the sound of a train going past that just keeps going.......
Royce and Susan McKean (the directors of the company that owns the vineyard) have a reputation for absentee landownerism that extends to Marlborough (They live in Sumner, Christchurch of course). Additionally, they also own Wairau Contract Labour Services. Could I be bold enough to think that they are using gang affiliates for vineyard work in both the Hurunui and Marlborough? Not that there's anything wrong with someone wanting to do a decent days work. But recent events in Marlborough have not endered the recently arrived gang presence to the locals.
Royce and Susan. You didn't have anything to do with encouraging a gang presence in Marlborough did you?
Perhaps the sound of mayhem on the streets will distract the population form the noise of the frost fans.
