A Vietamese family have finally moved back into their new home. Wellington's Wayan Rosie had torn their old house down but ran out of money to rebuild. Then a last-minute fundraising drive meant he could finish the job.

Wellington's Wayan Rosie, who tore down an impoverished Vietnamese family's home but had no money to rebuild, has finally finished the job.

In 2013, Rosie and a friend were travelling through Vietnam's Sapa region and visited the home of their guide, Lo Thi Lem.

They found her family living in "the worst home in the village", below road level, in a swamp, and covered in asbestos.

Rosie pledged to return to build them a new home and earlier this year did just that.

Of the $15,000 he expected he would need to raise, he managed to raise $6000.

But even after he added $2000 to the account himself, it was still not enough.

Undeterred he tore down the home earlier this year while the family moved in with neighbours.

But expensive retaining work meant he ran out of money before he could start rebuilding and faced the reality he may have to leave the family without a home.

In May, Stuff.co.nz did a story on Rosie's predicament in which he admitted, "I've actually really made a bit of a mistake not planning this project out properly".

Following the story donations starting rolling in, reaching his original $15,000 goal in a matter of days and the project could get underway again.

Earlier this week, the build was finally completed and the grateful family moved in.

"The amount of support I have received was overwhelming and some of the donations came from people that were not particularly wealthy. I have learnt to much about how the building industry in Vietnam works."

He now planned to start a new fundraising drive to build a home for a family made homeless by the Nepal earthquake.
