Players from a Tasmanian netball club claim to have broken the world record for the longest continuous game, having played for more than 62 hours.

The longest netball game on record lasted 61 hours and was played in Canada in 2011.

Players from the Generation Netball Club in Launceston began their attempt to break the record on Thursday night.

Parent Sally Stuart said they reached 62 hours earlier today and then voted to play on.

"We've got the 62 which beats the previous record, did they want to continue and try for the 72 and they unanimously said that's exactly what they want to do," she said.

"They want to get back out there and keep going."

The mostly 16 and 17-year-old girls plan to continue playing until tonight and leave the new record at 72 hours.

The record is yet to be officially verified.

Ms Stuart said it had been a massive effort from all involved.

While elated about their achievement, the girls admitted they had to push through pain, thirst and sleepiness.

"I was ecstatic but very tired," she said.

"There are 24 players involved, because in a regular netball team you are allowed to have 12, which is seven players on the court and five on the bench.

"So there's five on the bench who are resting, having a massage, having food, having drink, little cat nap here and there.

"They have pushed through injuries, pain, tiredness blisters, sleep deprivation."

The game has been played without breaks, although the rules allow a five-minute break for every hour of play and that time can be accumulated.
