"The driver was outside chatting with some people. I was only there for about a minute before he jumped in and pulled out across the road and kept heading out towards Muriwai beach direction.

Kiwis quickly flocked to social media to poke fun at the bizarre sight captured in Kumeu.
One person joked saying: "Taking advantage of the AA 12c discount. 'Do you want to use that today or accumulate?'"
"The $150 max limit is going to be annoying," another wrote.
"The war on petrol prices is real!"
The vehicle is believed to be a FV433 SPG Field artillery tank.
Tanks are legally allowed to drive on New Zealand roads, but rubber must be attached to the tracks to stop the tank chewing up the road and the gun needs to be disabled.
Even if the gun is disabled, the vehicle owner must hold a firearms licence.
In 2012 Christchurch man Gerard Dalry put his prized Abbot FV433, a 1966 ex-British Army tank on Trade Me with a buy-now price of $150,000.
The former owner says "it creates havoc wherever it goes". Photo / Supplied
The 'King of the Road' was fully roadworthy, with current rego and WOF, and a top speed of 60km/h.
The vehicle, with the number plate GBH4U, was armed with grenade launchers and a 105mm howitzer gun.
The killer machine spent most of its life based in Germany, patrolling borders along the Iron Curtain.
