St Mirren (loan)
After a spell training with the club on 1 January 2013, he joined Scottish Premier League side St Mirren on loan until the end of the season. At St Mirren, he teamed up with fellow Newcastle player Paul Dummett and was given the squad number twenty four, where he was an un-used substitute, in a 1–1 draw against Kilmarnock. Newton made his debut playing from the start on 19 January, in a 4–1 home defeat to Ross County. Newton's first goal for the club came in the Scottish Communities League Cup final against Hearts on 17 March 2013, when he collected his first senior medal following St Mirren's 3–2 win. Following the match, Newton says his first major final was a good one and playing in the cup final is such an honour. In addition, Newton says his thoughts about the goal: A week later, on 6 April 2013, Newton scored his first league goal, in a 2–2 draw against Motherwell, which was the last match before its split. His second goal came up on the final game of the season and provided assist for John McGinn, who scored the opener in the match, as St Mirren would win 3–1 against Kilmarnock. In the 2013–14 season, Newton returned to St Mirren on loan in his second spell. After making twelve appearance, Newton scored his first goal in his second spell in a 2–1 win over Ross County and followed the second the following week, in a 3–0 win over Partick Thistle. In January, Newton loan spell was extended until the end of the season, making this his first full season at St Mirren. Newton was a first team regular for the club, and made 41 appearances over the course of the season. The midfielder weighed in with five goals, scoring in his final match against Hearts on 10 May 2014 before his loan spell finished.
Newton moved back to the North-East signing for National League club Hartlepool United in July 2017. Newton scored his first goal for Pools in November 2017 in a 4–0 win against F.C. Halifax Town. Newton made 27 league appearances in his first season with the club. At the end of the 2017/18 season, Newton was transfer listed by the club along with six other players.
