DIVISION One pacesetters Goytre remain top, Cwmbran Celtic are the second-tier table's new leaders while there were fine Division Three wins for Newport YMCA, Panteg and Treowen Stars.
Goytre entertained bottom-placed Garden Village and their Plough Road HQ and defeated them 3-1 to maintain a one-point lead over namesakes Goytre United.
Callum Milles took his campaign total to four with the first with Sam O'Sullivan and an own goal accounting for the visitors, who have yet to win in seven games.
Monmouth Town striker Nick Harrhy's penalty ended a recent lean spell for The Kingfishers, who move up a couple of places to 11th in winning 1-0 at home against Briton Ferry Llansawel, but fellow-top flight clubs Risca United and Aberbargoed Buds both lost.
Risca fell one rung to ninth of 16 following a 3-0 home reverse at the hands of Aberdare Town while one-from-the-bottom Aberbargoed were 1-0 losers at Cambrian & Clydach.
It was third against second when Cwmbran Celtic hosted unbeaten-in-four Llanelli Town with the hosts moving above thanks to a 2-0 success plus previous table-topping Caldicot Town going down 1-0 at Pontardawe Town.
Celtic's goalscorers were Owen Cook and Owen Llewellyn as they registered their fifth win in seven starts while Caldicot fell to defeat for the first time six outings.
They drop to second place with the top-three places now filled by local clubs thanks to Undy Athletic's 3-1 home triumph over Llanwern.
There's no doubt Undy deserved the win, even thought they were not at their best, but Llanwern were rather unfortunate to concede in the manner in which they did.
They had already missed a good chance to go ahead via Stuart Patten then had a fair penalty appeal turned down before the hosts swept up the field to score via a cross-shot from Dan Jarman.
Undy went 2-0 up through the impressive Jarman after Luke Winter could have levelled at the other end and the contest was over on the hour mark when Llanwern goalkeeper Ashley Hart made a hash of a free kick from joint-manager Michael Flynn.
Llanwern brought on wideman Gareth Devle and came back into the game when he slotted home from close range on 73 minutes from a Richard Veale cross - although it ultimately proved to be only a consolation.
The defeat defeat for Llanwern and Croesyceiliog's 1-1 home draw with Tata Steel means they swap places at the very bottom of the table.
Indeed Croesyceiliog looked to be heading for their first win of the season at the fifth time of asking when they lead Tata through a goal from Lee Mason.
However their luck was again right out when the visitors equalised in the first minute of stoppage time and there is a danger Chepstow Town may also be heading into the relegation area after they lost 3-0 at Penrhiwceiber Rangers.
Abergavenny Town had relinquished the leadership of Division Three when losing 6-2 at Caerau the previous week and their defensive problems surfaced again in being beaten 4-3 by visiting Newport YMCA.
In an incident-packed second period in terms of scoring, all seven goals were produced with YMCA sailing into a 3-0 lead via Ben Lawrence, Darren Berry and skipper Alex Jenkins.
To their credit, Abergavenny struck back well to level through Aaron Norman (2) and Dean Morgan and looked to be heading for a point - until up popped Jenkins to score a last-minute winner.
Abergavenny are now fourth and YMCA remain sixth, but Caerleon are down a spot to fifth following a 3-1 defeat at Bridgend-based Bettws - where Mark Dunn scored their only goal.
Treowen are enjoying a much better season than in recent years and elevated themselves up a couple of rungs to eighth in the 18-strong table with a 4-1 home triumph over Ely Rangers.
Matthew Jones, Johnny Edwards, Shane Brewer and Stephen Parfitt were on target for manager Simon Evans side, although Lliswerry, Tredegar Town and Newport Civil Service all slipped down after falling to defeats.
Lliswerry are 10th from sixth after losing 2-0 at Treharris Athletic Western, Tredegar dropped one from 10th in being beaten 3-2 at home by table-topping Caerau while NCS are down two places to 16th following a 7-3 reverse at Cardiff-based STM Sports.
On target for Tredegar were Craig Hewitt and Ryan Carniff with Marc Gunter (2, including a penalty) and Matthew Palmer netting for NCS.
There was, however, an improvement for Panteg, whose 2-1 home success over Llantwit Major moved them off the very bottom of the table up to 14th - Tom Wise and Jon Butcher scoring in their first win at the fifth attempt.
