The blazing opener made light work of South Eastern's handy total of 173 at Jack Brabham on day two of the Western NSW Junior Cricket under 15s carnival.

An equally damaging knock of 71 off 65 balls from Dylan Melvey lifted South Eastern after they were in trouble at 5-57 but Kreuzberger's heroics stole the show in a nine-wicket victory for Mitchell.

He whacked 21 boundaries and batted for over two-and-a-half hours to carry his bat throughout a memorable innings.

It's the hosts' first win of the tournament, after a fairly hefty 103-run loss to the Wakatipu High School side on Monday.

The New Zealand boys were back at it on Tuesday, too, key batsman CJ Kemp guiding Wakatipu home with a half ton in his team's pursuit of Northern District's all-out total of 102.

The kiwi gun proved unstoppable as his side ran down the total at better than a run a ball, coasting to 1-108 two balls into the 17th over.

Isaac Craddock's lone-hand of 37, off just 29 balls, proved a rare bright spot in an otherwise tough day for the Northern Districts boys.

Meanwhile, Mosman enjoyed a six-wicket win over Wagga on the back of Axel Bailey's 36 and Elliot Evans' eventful two over spell that netted 4-3.
