A Lower Hutt father is pleading for drivers to slow down after the third crash at his property in a year.

Cars went through the fence of the Naenae property in January last year and on Boxing Day.

At 12.30 this afternoon it happened for a third time.

After the second crash, property owner Blair Ansell lined the berm with six two-tonne concrete blocks in a bid to keep his family safe.

He said that's all that stopped the car this morning from crashing through into the front yard where his children play.

"My daughters and my sons both play on that trampoline continuously. Thankfully they weren't home today, they were both at kindy so we're just lucky my kids haven't been killed this time.

"Just slow down. They're lucky they haven't killed a kid, they're lucky they haven't killed a pedestrian or someone walking on the footpath, or worse - they could have killed a family.

Ansell said he's ordered 15 more concrete blocks and he'll build an entire wall around the corner if he has to.

Ansell's wife Louise told the NZ Herald that many cars take the corner too fast.

"We feel really unsafe . . . I don't feel so bad about it at night because the kids are inside. I don't feel like I can let my kids go out and play if it was daytime."

The couple went to the Hutt City Council for help after the first incident, but nothing has happened.

"I don't care what they do, they just need to slow these guys down. We didn't buy this house to have our kids hurt."

Since news of the Ansells' safety measures broke, several neighbours have been in touch with them complaining of similar issues.

"One guy down the end of the road, he calls [his] corner the corner of doom because people keep going through his fence," she said.
