[1] Stan Prentice began playing for the Richmond Rovers club based in Grey Lynn, Auckland in 1924 aged 21.

[4] On October 10, 1925, he was part of the Richmond 4th grade team which played curtain-raiser to the Auckland v Queensland match at Carlaw Park.

Richmond were in their 5th season in the senior grade of the Auckland Rugby League and finished 5th of 8 teams with a 3 win, 8 loss record.

Amazingly Prentice was selected in a series of trial matches to assist the selectors in choosing the New Zealand side to tour England and Wales in just his first season of senior football.

[31] Prentice scored 2 more tries in a match for Auckland where they thrashed Canterbury 66–26 in front of a large crowd of 15,000 at Carlaw Park on July 21.

The Auckland Star wrote “one confidently expects that Prentice and Wetherill will be the New Zealand … five-eighths pair for the first Test, seeing that they combine perfectly, and can each play their respective parts to a nicety.

[35] The prediction proved correct as on August 2 Prentice was named to make his debut for New Zealand in the five-eighths alongside Wetherill.

Early in the match “Prentice electrified the spectators by lifting Sloman, the English fifteen stone front row man, clean off his feet”.

[36] The Auckland Star wrote that Prentice produced “superb defence and glorious tackling [and] took all on the principal that the bigger they are, the better they fall, and not once in the game did he fail New Zealand”.

[39] On August 11 Prentice played for Auckland against the Great Britain side but this time went down 26-15 before 25,000 spectators at Carlaw Park.

At one point “Prentice and Bowen were cautioned for rough play” after “fighting on the ground” with Frank Delgrosso being carried off the field on a stretcher as a result of this ‘incident’.

[43] The Otago Daily Times stated that “probably the best back on the New Zealand side was Prentice, who put in no end of clever work”.

[46] Prentice then returned to Auckland and finished the season playing 4 further matches for Richmond including the Labour Day tournament final loss to Marist Old Boys 12–5.

[49] Prentice was offered terms by Wigan and sent his own demands back which were accepted however he had difficulties in getting away from his position in New Zealand and ultimately stayed.

Two weeks before his 4 try performance Prentice had been sent off in a match with City Rovers after an “argument” with fellow New Zealand international Steve Watene who was also sent from the field.

His fellow five eighth for the match was Hec Brisbane while ex-All Black Bert Cooke who had recently joined Prentice at the Richmond club was in the centres.

Tragedy struck the Richmond club on October 4 when senior play Harry Johns died as the result of head injuries suffered in a boxing match at the Auckland Town Hall the previous evening.

[60] At the end of the season Prentice was chosen for the ‘Rest of Auckland’ side to play against Marist Old Boys in a charity benefit match for former player W. Hanlon who needed assistance to return with his family to New Zealand.

[66][67] In the second victory it was said that he, along with Roy Powell and Jack Satherley played fine games and “prevented the half-backs, [Richard] Daly and Carey from going far”.

[68] He was responsible for Richmond's only try of the match after kicking through from a scrum and with [Stan] Robinson injured he failed to secure the ball and Tony Milicich scored.

[69] Late in the season Prentice also played for Richmond in their Max Jaffe Cup game against Marist which was to decide the ‘best club team in Auckland’.

[74][75] The 1934 season began with reports in late April that he "underwent an operation for appendicitis recently, and, although he appears fit, he will probably not be in his best form for a time".

In mid August Richmond toured Taranaki and the Hawke's Bay where they played both local representative sides and lost 23–22 and won 37–11 respectively.

[83] Earlier in the season on June 30 Prentice played for Auckland despite sustaining a rib injury the week prior in a match for Richmond against Ponsonby.

It was notable for the fact that he had seemingly retired at the beginning of the season for he did not debut for Richmond until July 13 when they were playing their round 13 match against Marist where he scored a try in a 22–0 win.

Auckland lost a hard-fought match by 16 points to 8 with Prentice partnering with Arthur Kay in the five eighth positions with Roy Powell at halfback.

[93] Prentice had done enough in the New Zealand selectors eyes and was chosen to play in the first test against Australia on September 28 at Carlaw Park alongside Kay and Powell.

[97] Unfortunately for Prentice he suffered a leg injury during the match and despite initially being selected for the second test he was unable to play and was replaced in the side by recent rugby league convert, and ex-All Black Herbert Lilburne.

The following Saturday saw Prentice recalled to the side for the Third Test once again at Carlaw Park where he was joined by a new five-eighths partner in Brian Riley with Eric Fletcher at halfback.

He also orchestrated New Zealand's first try which opened the scoring when he received the ball from a scrum near half-way and “cross-kicked with nice judgement … and Riley, following through fast, gathered in his stride and pranced across”.
