Law changes are likely this year, as the Government moves to review red tape.
Regulatory Reform Minister Rodney Hide says the review will start with simple issues which are easily solved.
He says law changes will sort out anomalies in shop trading hours, as well as overly-complex rules for fencing swimming pools, and registration rules for professionals from overseas.
Mr Hide says the Building Act will also be tackled, but that will take longer.
Local Government New Zealand welcomes the review.
Chief executive Eugene Bowen says red tape adds as much as $50 million to the cost of administering the Building Act and consultation requirements for councils.
