There was a M7.8 oblique thrust earthquake in New Zealand. It was more thrust than strike-slip. The plate boundary fault there, the Alpine fault, is SE dipping and has oblique right thrust motion overall. But, I don't think it is overall that much thrust. The ESE-dipping nodal plane (link) has a right-lateral component. I'm assuming these are lower hemisphere focal mechanisms; I've always assumed that and probably checked a long time ago.

There are parallels with the San Andreas. The San Andreas fault proper is commonly non-vertical (e.g., Fuis). The Loma Prieta quake was oblique slip. I'm not sure about the North Palm Springs quake in the 1980s; it was on moderately-dipping fault. Elsewhere, the San Andreas is thought to be nearly pure strike slip with the thrust components partioned off onto other faults. This is presumably known from trenching. But, perhaps it would not be impossible for the San Andreas to fire off another oblique thrust quake. A branch of the Santa Cruz Island fault at the Moore Meadows (?) surfing spot on the east coast of the Island has a 10 m-thick 100% exposure of the fault strand; the last slip on it was mostly strike-slip with some reverse and the one before that was more reverse than strike-slip. You can tell the relative ages of slips because the fault surfaces cut right through and are getting mineralized (gypsum).

That stretch of New Zealand is mountain and I think Wilderness, but assuming it was the ESE-dipping plane, the cities off to the east must have had a good shaking. There must have also been a bunch of landslides.
