Relegation-threatened Swallows fell to their second consecutive Absa Premiership draw as they failed to hold onto their lead once again.
Vuyisile Wana opened the scoring for the Soweto side in the 23rd minute before Atusaye Nyondo grabbed an equaliser shortly after the half-time break.
Nomvete, who won the Absa Man of the Match award, said his team lost concentration at a critical stage in the match, which saw them surrender two points to the home side.
"Definitely [not the result we wanted], we came with everything tonight and it didn't happen," said Nomvete.
"As players we are very disappointed because were aware that we had to pick up the three points, but it just happened that we ended up at 1-1.
"I think we lost the concentration at the back, that's why they got the equaliser.
"We have to fix the problem [it's not the first time] it happened today," he added.
