Local government across the border announced that their lockdown would continue for a minimum of three weeks and as a result the Cymru Premier have decided to postpone their fixtures.
TNS, who last played on December 19, will now not play until the end of February at the earliest.
A statement from the league read: "Following the First Minister’s announcement that the lockdown in Wales will continue for at least another three weeks, the JD Cymru Premier has decided to postpone the remaining Phase One fixtures.
"Although fixtures between professional clubs are permitted to take place during this Alert Level 4 lockdown of the Welsh Government Control Plan, the league fully takes into consideration the current public health crisis.
"The JD Cymru Premier and its clubs continue to urge everyone to follow the Welsh Government guidelines to limit the spread of COVID-19 in order to keep people safe and lessen the impact on NHS Wales."
