You will need:
- A trailer (or you may wish to get your topsoil delivered)
- Spray pack
- Dingo, cultivator and rotary hoe
- Water-filled hand roller
- Spade and rake
- Topsoil, fertiliser, lawn seed
Step 1: Use a herbicide spray to kill off any existing lawn and weeds.
Step 2: After spraying, remove excess topsoil and rotary hoe the area. Leave for a few weeks to ensure there is no further weed growth. Repeat step one and two as necessary. 
Step 3: Spread a good base of new good quality topsoil, with the gradient running away from any buildings to allow for water runoff. 
Step 4: Aerate the topsoil with a cultivator or rake, removing any large clumps. Add fertiliser if desired – consult your local landscape supplier for the best fertiliser for the type of grass you wish to sow.
Step 5: Lightly compact the area using a water-filled hand roller, being mindful to avoid over compressing. 
Step 6: To sow your seed, work in a metre square grid pattern, spreading seed both horizontally and vertically within each metre of the grid to ensure even coverage. 
Step 7: Water regularly, but avoid pooling of water as this can wash away your seed.For further information please go to www.hirepool.co.nz.
