With only two days to the Wellington 7s, the Wellington police say that they will not allow rugby fans to wear the skimpy swimsuit of movie star Borat at the tournament this weekend.

The sevens is one of the highlights of the Wellington social calendar and those who do not dress up are among the minority, but police are warning people to be careful when choosing their outfits.

Police have been working closely with the stadium, the rugby union and the city council officials and the steps being taken include:

- A public liquor ban running from 5pm to 8am on both Friday and Saturday.

- Security officers searching bags to ensure alcohol isn't carried into Westpac Stadium.

- Enforcing a stadium dress code which includes leaving weapons such as imitation swords or firearms at home.
