An 18-year-birthday in Stratford turned sour when locals who saw the invite in Facebook gatecrashed the party.
What was supposed to have been a private message on Facebook, somehow got onto the local Facebook.
"The biggest thing is that it was locals who showed no respect for us and our property," says mum Shauna Goble.
Around 2am they received a notice from the Stratford council's noise control to turn it down.
"That is when we turned everything off."
But it was trying to get them to go, when the biggest problems started, she says.
Her warning to parents and other people using the internet to invite friends over is to make 100 per cent sure that a private message is indeed private.
"Most of the trouble," she says, "was caused by females who incited some of the other males and were abusive and some even threatening."
Adding fuel, most of her son Michael's presents were stolen.
Shauna says the party started with a hangi around 6.30pm.
"Twenty odd answered and we catered for around 50. His work, rugby and kapa haka mates joined for a couple of hours and then left. A big group turned up after tea, the majority from Stratford. They were not his friends. Many of them turned up already intoxicated."
She says the invite was to bring your own drink, but that they checked IDs, where needed and possible.
"Some turned up with drugs, but they were quickly kicked out," she says.
She says not everyone agreed that the party got out of hand, but she says it needs to be said: make sure who you invite. With even a number of 12-year-olds pitching up, she asks the parents: do you know where your kids are?
