.new isn't a function when deploying contract (web3)

Question

I'm trying to deploy contracts using Ganache but I'm getting the following error.

I have my ABI and contract address defined, all other functions with respect to interacting with the contract work, however I cannot create a new one. Any ideas? Thanks.

The code is below...

newContract: function(error, result) {
  createContract.new(quantity,name,decimals,symbol,{from:account,gas:21000}).then(function(instance) {

  if (!instance.address) {
    console.log("Contract at: " + instance.transactionHash + " waiting to be mined");

  } else {
    console.log("Contract mined. Here it is: " + instance.address);
    console.log(contract);
  }

  console.log(instance.address);    
});

This is the error -

TypeError: createContract.new is not a function

Update: It is initialized via

var createContract = web3.eth.contract(createContractabi);

I'm wondering if the error is being generated as my currentprovider is giving an error...

Both createContract.setProvider(this.web3.currentProvider); and createContract.setProvider(web3.currentProvider); were tried.

However, both fail, with the errors

TypeError: Cannot read property 'currentProvider' of undefined

and

TypeError: createContract.setProvider is not a function

respectively.
