Property owners are also asked to check power lines on their land to ensure there is a good safety margin between the power lines and trees.
A common tell-tale sign is brown tips of branches where arcing has occurred previously, when the tree and power lines have come into contact with each other.
If work to clear the lines is required, land owners are encouraged to contact their local power company, which will be able to tell them which tree contractors in their area are approved to carry out this work.
Mr Wishnowsky is encouraging anyone with information to contact the Wairarapa Rural Fire District or police regarding two fires at Norfolk Rd on Saturday evening, which were started by fireworks from a moving vehicle.
Mr Wishnowsky said six fire appliances spent six hours protecting property at risk.
A forestry crew remained overnight to monitor the two sites.
