The Moascar Cup was won by the New Zealand Mounted Rifle Brigade during World War One in a services rugby tournament in Egypt. It was brought back to New Zealand and it was decided that it should become a challenge cup for secondary school rugby.

The first match was played in 1920 between the two best 1st XV’s in the country Palmerston North Boys High School and Christchurch Boys High School and the match was played at Athletic Park in Wellington. Parliament was suspended so that politicians could attend the game. When the game reached 0 – 0 it was decided that the next team to score would win or the team that made the ball dead would lose. PNBHS forced the ball down behind the goal-line and therefore should have been deemed to have lost the match. The referee, however, decided to let the match play on but Palmerston North kicked the 22 out on the full so the game and the Moascar Cup went to Christchurch.

The Moascar Cup was in the North Island from 1922 until 2004 when the 1st XV coached by Mr Ralston and Mr Murphy and managed by Mr Fraser won the cup from Hastings Boys’. The CBHS 1st XV, later coached by Mr Taylor and Mr Bone went on to set a record of 22 defences from 2004-2007, before losing the cup to St Bede's College in 2007.

On Saturday 28th July, CBHS played the holders Nelson College who were in their 16th defence of the cup. On a beautiful Nelson day, but with a soft ground underfoot, there was a big crowd in attendance for what shaped as a great game.

The first half was dominated by the challenger who led 12 nil at the break courtesy of tries to Yoji Yabe and Ben Lopas and a conversion to Ollie Lewis.

The second half began with CBHS dominating and a penalty again slotted by Ollie Lewis took the score out to a comfortable 15 nil. However, Nelson was much too proud a side to simply roll over and came charging back with a converted try to narrow the gap to 15-7. Again CBHS responded and with a further penalty and conversion to Lewis, following a good try to replacement number eight Corban Harding, the gap again eased out to 22-7.

The final stages of the game saw one last charge by Nelson resulting in a late try to narrow the margin to 22-12.

The cup was heading back to Christchurch after a brave performance, the 13th win for CBHS in 13 games this season.

The aftermath of the game understandably saw contrasting emotions from the two sides but will be best remembered for an outstanding speech by Christchurch Boys’ captain and Head Boy Louie Chapman, who showed both humility and great respect in his acceptance of the trophy.

The Moascar will be defended for the first time by CBHS in the UC semi-final on 18 August.
