I have the North Nova v2 in 5m and 6m which I really like!

Both wings have leaked in the same area - where the handles join the strut.

I wondered if any other North v2 owners have had the same issue and if it's a weak spot?

Put your hand down the strut and feel the area for sharp edges/bolts sticking through etc.

Assuming they're still in the warranty period, contact your dealer and let them know. Probably a slow leak around the valves (on the bladder). Both armstrong and duotone took care of this type of issue for me under warranty (either sending a new bladder or paying for the repair).

Ozone and Blue Planet have good youtube videos on wing repair if you want to DIY.

I heard from the wing repairer earlier. He took the bladder out of the 6m and found two holes either side of the bladder, opposite each other. He said it likely happened when it was deflated and I had knelt on it or rubbed it somehow and a sand grain or similar created the holes.

I often kneel on the wing/s when deflating to get the last of the air out, so it appears the damage is likely self inflicted and I need to change my deflation technique!

Good to know I'll have to be careful when packing!

Depending on where you are in the country, affects the type of damage and repair.
We have a lot of repairs, both kite and wing, where riders set up and pack down on grassed areas.
Especially here in WA, late season rain, followed by hot spells mean we get a sudden spurt of double gees growth followed by drying out, The super sharp seeds sit just below the grass surface and are sharp enough to go through a leading edge or stut, through the bladder both sides front and back, especially if you are trying to force air out of the bladder.
Set up and pack up on the sand where it is much easier to spot any sharp objects.
