Round Up: Principality Premiership
The All Blacks are going for a third straight Premiership title, but centre Jones scored on either side of the break and the home side showed grit to hold out for a 25-21 victory.
Former Wales outside half Arwel Thomas kept Neath in touch with four goals, but opposite number Craig Evans matched him kick for kick as the Blue and Blacks secured a top-five spot in the league.
Pontypridd had the chance to go top of the table with a victory at Maesteg, but the Valley Commandoes came up short in a 21-16 loss. Maesteg back rower Carl Hocking scored a second-half double to get his side home after the teams were locked at nine points apiece at half-time.
Instead, Ebbw Vale returned to the top of the pile with a 26-all draw over Glamorgan Wanderers.
