[13] The Auckland Star said that he "made a very promising debut at half-back, and when he opened up the play, [Brian] Riley and [Walter] Stockley with clever, incisive running gave the Ponsonby three-quarter line plenty of opportunities".

[15] Then the following week in a 17–2 win over Devonport United the Herald said "great credit for Ponsonby's success must be given to Halloran, halfback, and W. Stockley, first five eighths.

[17] The following week Ponsonby lost to Richmond 16-4 and Halloran had "more limited opportunities than usual [but] was still a notable half-back- a quick thinker, resourceful and varied in his methods".

[28] The next week he was moved back to halfback in Ponsonby's 11–7 win over Marist Old Boys at the Onehunga Recreation Ground (Waikaraka Park).

The herald said that Vincent Axman was a surprise inclusion at halfback and that "Halloran, the young Ponsonby half, has shown better all-round form during the season and can be accounted unlucky to miss selection".

[43] The next week in a loss to Richmond he "played a good game at halfback, starting his backs smartly and doing great work on defence".

[44] In a summation of the players in form in the Auckland competition the Herald said that there was "plenty of talent offering for the position of halfback for the representative team.

[52] The A team won 22–19 with Halloran replaced at halftime by A.S. O'Connor of Wellington in a pre-arranged move so that the New Zealand selectors could see him play.

The newspapers contradicted one another with the Auckland Star saying Halloran "was in fine fettle behind the Ponsonby pack" but the New Zealand Herald said he "was a weak link" behind the scrum.

[57] The 1936 season saw Halloran play 19 games for Ponsonby, scoring 5 tries, while he also went on to make his one and only appearance for the Auckland representative side against Wellington.

The Ponsonby team was to be coached by the recently retired All Black legend and New Zealand rugby league representative, Bert Cooke.

[59][60] In a round 1 loss to Richmond by 21 points to 10, Halloran scored a try, and at halfback he "played a good game, his all-round form being reminiscent of that which made him outstanding three seasons ago".

Halloran was chosen by selector Bert Avery at halfback to play alongside his Ponsonby teammate Walter Stockley who captained the side.

[73] Auckland won the early match 25–22 with the Herald publishing a photograph of Halloran shaping to kick after gaining possession from a scrum inside their own half.

[76] He was named in the reserves for both teams by Bert Avery for the trial match, which was to give himself and fellow New Zealand selectors Jim Amos and Thomas McClymont a chance to see the talent.

[90] In Ponsonby's next match, a 7–3 win over Manukau the Herald wrote that he and Stockley were "too flat footed" with Halloran "often taking his passes from the halfback standing".

[96] Then in an upset 10–9 win over eventual champions, Richmond, Halloran "was outstanding for the winners, sending the ball away splendidly and defending soundly".

[98] Later in the week the same newspaper wrote that "his tackling and covering on defence saved his side repeatedly, while he showed cleverness on attack and was responsible for Ponsonby's second try".

[100] He was then named in the New Zealand trial match on July 28 where he was chosen in the Possibles team at halfback despite having played the entire season to this point at first five eighth.

The Auckland Star wrote "Mahima and Halloran provided a sharp contrast in half-back play, the former rugged and solid, the latter showing refreshing enterprise in attack".

The Herald wrote that "Mahima must be considered unlucky not to get the halfback position, as he played a brilliant game yesterday and has stronger claims for selection than Halloran".

New Zealand caused an upset by winning the match 16-15 though they were helped by Australia suffering several serious injuries and playing much of the second half two men short.

[113][114] In a summary of the match it was said that he "tackled well and sent out good passes, but the transfers of all the backs lacked the snap and precision which characterised the work of the Australians".

They then defeated North Shore in the first round of the Roope Rooster knockout competition before a win over Mount Albert in the semi final.

Ponsonby put in one of their "poorest performances of the year" with the inside backs "standing flat-footed and passing the ball shoulder high".

Halloran played at his more familiar position of halfback however he "was caught in possession of the ball too often, and selfishness on his part also spoiled many promising attacks".

[126] They then beat North Shore 16–7 at the Devonport Domain in round 7 with Halloran showing speed in some back work which saw Brian Riley scoring.

[127] Against Marist a week later Halloran achieved the rare feat of a conversion and a penalty as he had almost never taken goal kicks, though Ponsonby lost 13–7 in the main match at Carlaw Park.

The following week following an upset win over Manukau the Herald wrote that the "loss of Stockley and Halloran was compensated by the good play of Carr... and Rush" two promoted juniors.

[130] He was not mentioned in connection to any of their following 4 matches and then on July 19 it was reported that he and John Stockley (brother of Walter) had transferred to Northcote where they would join their senior B side.
