He was released at the end of a three-month contract with Stockport in November along with current Tiger Richard Sneekes. In Van Blerk's last game for County - a 6-0 defeat at Preston - he was sent off after only half an hour. He played in twelve other Division 1 games this season for the Hatters plus the 3-0 defeat of Carlisle in the Worthington Cup.
Van Blerk also played alongside Sneekes at West Brom, where the Aussie made over 100 appearances in 3 years, netting three goals. He had signed for the Baggies from Manchester City for a £250,000 fee in March '98. He only made 10 starts for them in an eight-month spell.
He began his English career at Millwall. He spent three seasons at the Den after the Lions bought him for £300,000 from Go Ahead Eagles, before leaving on a free transfer to Man City in '97.
Van Blerk - capped 33 times by his country - said: "I think the experience I've gained over the past few years will help me a lot and all I want to do is give the side that little extra push in the promotion race.
"It looks as though promotion could be on the cards this time around and obviously it's great to think that I could be a part of that.
